The plan is to look at increasing max cars in race sometime after the big update is released.
We need to see how the new physics works on everyone's computers (in the multithreaded system, which should help, if CPU has at least two, but preferably four cores) and after evaluating that we can see how the performance will be when extending to 48 cars in race.
The purpose of this current test patch is to release an official version with much better mod support than in the currently official version, so that mod makers can keep making nice mods while I get on and finish the physics for the new version (improved tyre physics and much better graphics, with significantly updated tracks) that we are all waiting for.
Optional update for LFS_restart.exe
Hello Racers.
The latest (Test Patch D51) versions of LFS and LFS Editor have new icons kindly provided by Flame CZE.
These icons look better and contain a larger icon image that works well with modern versions of Windows.
If you don't use the test patch, you will get the new icons when you update to the official version (soon to be released).
But there is one file that can't be updated when you are getting an update from the auto update system, and that is the small program file LFS_restart.exe which normally sits in your LFS folder, waiting to be used when you get an update for a new version.
So if you would like LFS_restart.exe to have a nicer looking icon, click this link to download a zip file containing LFS_restart.exe which you should save into your LFS folder, overwriting the existing file.

I plan to do that.
I moved your post to Test Patch D50 thread
As far as I knew there would only be these rare issues, such as OOS in the known cases listed in the first post. I'm not investigating OOS cases to see if they are the ones described or some other reason. Unless a D50 guest gets an OOS on a D50 server.
I didn't know the new test patch would be so popular. I'm not sure how important it is to bring a test patch into the official server rental system, although it looks more important that I first thought.
Obviously some testing was required. It looks pretty stable but I have had one error reported, don't know if it's something new.
Also I see a lot of "WOULDBLOCK" UDP errors on TC. I don't know if this is due to the higher bandwidth and if I can do something about it.
So the general idea is we are just testing and I need to have a look at issues, and due to the popularity of the patch, it is worth considering if D50 servers should be selectable.
As tankslacno says, these commands need a new version.
Please bear with us, the situation is as I've described.
Updates still planned for Test Patch:
[simple updates that I can add to a compatible version]
Misc:
- consider improved support for stretched tyres

Various improvements to improve the overtaking decisions
Overtakes are considered on a group instead of individuals
Better estimate of the possibility and duration of a pass
Pass decision from low speed now allows for acceleration

Misc option "Full physics for remote cars" is enabled by default
- low res physics previously used for cars other than the 4 nearest
- option approximately doubles CPU usage by physics in multiplayer
- could cause issues at turn 1 with many cars depending on PC power
- use profiler display to check CPU usage with the option enabled
- see profiler by pressing car icon then P in Misc/Graphics options
Engine damage repair in pit stop
- yellow counts as minor damage (6 seconds)
- red counts as major damage (12 seconds)
Team arrow colours on small map are now enabled by a host option
- arrows on non-race small map take colour of first name character

FIX: Remote car using pit speed limiter did not move smoothly
FIX: Crash enabling filter in List of Hosts after all were disabled
InSim:
IS_CPP packet with Time = 0 is instantly processed (not stored)
- allows it to be followed immediately by an IS_CPP with Time > 0
FIX: ZByte was not set in IS_OBH packet
New commands:
/status none|F9|F10|F11|F12|next|prev - sets status screen
E.g. /status next will cycle through the F9 to F12 status screens
(you could assign it to a CTRL+ or ALT+ key and then a wheel button)
/liveset and /pitins - do the functions of F11 and F12 menus
You can use operators:
= (set value)
+= (add to value)
-= (subtract from value)
Examples:
/pitins ftyre = r3 : change front tyres to R3 in pit stop
/pitins rtyre = super : change rear tyres to road super
/pitins fpressure = 1.1 : set front tyre pressure to 1.1 bar
/pitins fpressure += 0.1 : increase requested pressure by 0.1 bar
/pitins cancel : cancel all pit instructions
/pitins tyres always : change all tyres
/pitins tyres 20 : change tyres if wear > 20%
/liveset bbal 60 : set brake balance to 60%
/liveset rarb -= 0.1 : decrease rear ant-roll bar by 0.1
Available options for /pitins:
fuel, tyres, repair, symmetric
ftyre, fcamber_l, fpressure_l, fcamber_r, fpressure_r, fwing
rtyre, rcamber_l, rpressure_l, rcamber_r, rpressure_r, rwing
cancel, fcamber, fpressure, rcamber, rpressure
/pitins pressure commands can accept unit (psi/bar) (no unit = bar)
E.g. /pitins fpressure 30 psi
Available options for /liveset:
bbal, farb, rarb
Multiple commands on single line:
Multiple commands can now be added on a single line which sometimes
can avoid the need for a script file, e.g. to set a button to
change tyres in pit stop, you could use a double command:
/pitins ftyre super /pitins rtyre super
NOTE: some commands cannot be followed by another command:
/say /echo /join /rcm /pass /msg /altf /ctrlf
Maximum length of command and F key text increased to 95 characters
Wider text display in CTRL+ and ALT+ tabs in controls screen

FIX: Can now reset at the end of a pit stop (e.g. fallen bike)
AI overtaking:
Various improvements to improve the overtaking decisions
Overtakes are considered on a group instead of individuals
Better estimate of the possibility and duration of a pass
Pass decision from low speed now allows for acceleration
When planning a pass time is allowed to pull in after pass

- previous location of tyre contact is better estimated (for forces)
- most noticeable when viewed car had not been on screen for a while
- e.g. after tabbing to another car or fast forwarding a replay
Misc option "Full physics for remote cars" is enabled by default
- low res physics previously used for cars other than the 4 nearest
- option approximately doubles CPU usage by physics in multiplayer
- could cause issues at turn 1 with many cars depending on PC power
- use profiler display to check CPU usage with the option enabled
- see profiler by pressing car icon then P in Misc/Graphics options
Engine damage repair in pit stop
- yellow counts as minor damage (6 seconds)
- red counts as major damage (12 seconds)
Team arrow colours on small map are now enabled by a host option
- arrows on non-race small map take colour of first name character
- option is not yet available but is coded as /teamarrows=no/yes
Cancel button and ESC key to cancel the process of joining a host

FIX: Remote car using pit speed limiter did not move smoothly
FIX: Crash enabling filter in List of Hosts after all were disabled
InSim:
IS_CPP packet with Time = 0 is instantly processed (not stored)
- allows it to be followed immediately by an IS_CPP with Time > 0
FIX: ZByte was not set in IS_OBH packet
New commands:
/status none|F9|F10|F11|F12|next|prev - sets status screen
E.g. /status next will cycle through the F9 to F12 status screens
(you could assign it to a CTRL+ or ALT+ key and then a wheel button)
/liveset and /pitins - do the functions of F11 and F12 menus
You can use operators:
= (set value)
+= (add to value)
-= (subtract from value)
Examples:
/pitins ftyre = r3 : change front tyres to R3 in pit stop
/pitins rtyre = super : change rear tyres to road super
/pitins fpressure = 1.1 : set front tyre pressure to 1.1 bar
/pitins fpressure += 0.1 : increase requested pressure by 0.1 bar
/pitins cancel : cancel all pit instructions
/pitins tyres always : change all tyres
/pitins tyres 20 : change tyres if wear > 20%
/liveset bbal 60 : set brake balance to 60%
/liveset rarb -= 0.1 : decrease rear ant-roll bar by 0.1
Available options for /pitins:
fuel, tyres, repair, symmetric
ftyre, fcamber_l, fpressure_l, fcamber_r, fpressure_r, fwing
rtyre, rcamber_l, rpressure_l, rcamber_r, rpressure_r, rwing
cancel, fcamber, fpressure, rcamber, rpressure
/pitins pressure commands can accept unit (psi/bar) (no unit = bar)
E.g. /pitins fpressure 30 psi
Available options for /liveset:
bbal, farb, rarb
Multiple commands on single line:
Multiple commands can now be added on a single line which sometimes
can avoid the need for a script file, e.g. to set a button to
change tyres in pit stop, you could use a double command:
/pitins ftyre super /pitins rtyre super
NOTE: some commands cannot be followed by another command:
/say /echo /join /rcm /pass /msg /altf /ctrlf
Maximum length of command and F key text increased to 95 characters
Wider text display in CTRL+ and ALT+ tabs in controls screen

Editor Test Patch D50 (now D64)
Hello Mod Creators,
Here is an update for the LFS Editor.
Editor 0.7E is now available!
https://www.lfs.net/forum/thread/95664
Changes in Editor D64:
FIX: Subobject transparency was not visible in special draw mode
Changes in Editor D63:
Vehicle editor:
New switch options for rotator and slider: signal / light switch
New flip function "with driver" (move across with driver / no flip)
Spinner objects now stop nicely at the default position
Changes in Editor D61:
Modeller:
Message selecting triangle in another subobject uses subobject name
ALT+click on triangle in another subobject to select that subobject
FIX: Spoke editor duplicate and delete buttons in texture page mode
Rim editor:
Added CTRL+D (duplicate) and CTRL+N (new point) keys
Changes in Editor D60:
Graphics:
Support for stretched tyres (when rim is wider than ideal)
Rim editor:
You can now see and type / copy / paste selected point coordinates
Removed direct drag on point and added diagonal drag handle instead
Snap to grid only works on the relevant drag axes (X, Y or both)
Modeller:
New button to show subobject's axes (beside "rotate" button)
Changes in Editor D59:
Vehicle editor:
Selected suspension point can (again) be adjusted in SHIFT+L view
Subobject indicators left / right now relative to whole vehicle
FIX: Passengers were not updated when selecting a different setup
Modeller:
New flood select function to select all triangles by point sharing
- different from CTRL+SHIFT+LMB (select related triangles by edge)
- ALT+RMB selects all connected triangles regardless of properties
- triangles are considered connected if they share a single point
FIX: Keep merged subobject feature was controlled by wrong option
Changes in Editor D58:
Moving subobjects:
Popup headlight system generalised for moving objects with switches
Subobjects can rotate a set angle, slide or spin at a given speed
This can be connected to switched lights / ignition / horn / siren
New test system in vehicle editor "Class / Inputs" tab (top left)
Changes in Editor D56:
Skin mappings that move with driver side swaps no longer avoid flip
Transparency now works correctly with popup headlight objects
Popup headlights now support flip function
Changes in Editor D54:
Lights tab in Vehicle Editor:
FIX: Subobject lights did not visibly update in editor when adjusted
Modeller:
Merge subobject dialog : use selected layer / keep existing layers
Improved layer selection (tooltips change when CTRL is pressed)
- in orange/yellow mode : CTRL+RMB sets the selected layer
- tri mode : CTRL+LMB - select all triangles in layer
Modeller hotkeys / shortcuts:
Keys to select modes: numbers 1 to 8 (subob
SHIFT+M / SHIFT+S - show main / show subobs
Changes in Editor D53:
Lights:
Lights now work on subobjects (e.g. bike handlebars)
New object type "Popup headlight"
- set axis, angle and time of rotation in modeller
- test using slider bar in vehicle editor Lights tab
Modeller:
Option to keep an empty (rotated) subobject after "merge into main"
- and break off main object into rotated subobject works as expected
- for example the following sequence of operations is now possible:
1) rotate a subobject to convenient orientation for modelling
2) merge into main but keep the empty rotated subobject
3) model and map the subobject in that position
4) break off into the rotated empty subobject
Changes in Editor D52:
Wheel object visibility:
No change in editor but game now matches the editor
- "inside covered" or "open wheel" only affect logo and lighting
- visibility of brake disc and spoke object is no longer affected
Rim and spoke objects:
Rim now gets material properties from first mapping in spoke object
Spoke object can have more than one texture page, including _ALP
- for example a chrome material can now be added as first mapping
- and in that case the rim would also use that chrome material
- no alpha sorting: transparency should only be used for overlays
Lights:
Multiple mappings per special name e.g. more than one l_head
- a second word is allowed e.g. 'l_head front' / 'l_head top'
- the second word is only to make it clearer for the mod creator
- extra names such as l_sbrk and l_tbrk are no longer needed
- reduced number of special light mapping names from 18 to 12
- mesh configurations are now fully supported by the lights
- e.g. separate mappings like 'l_head stock' and 'l_head sport'
- NOTE: maximum of 4 mappings per special name in a configuration
- NOTE: all mappings in use in a group must share a single texture
Dashboard:
Option: Show low and high beam icons simultaneously
- (shows icons for lights less than the current light switch)
Option: Show dim icons when not illuminated [default yes]
- (allows you to disable the faint image of icons that are off)
Option: Show dim segments of digital displays [default yes]
- (disable the faint non-illuminated segments of gear / speed)
Editor options: Dash lights off/on / Expand dash texture display

- "high" lights are for vehicles with separate high beam lights
- "extra" lights are for unspecified vehicle-specific purposes
/light head side - switches on side lights
/light head low - switches on low beam
/light head high - switches on high beam
If l_side separate there is an option to keep them on with main
If l_side not separate you can choose to share l_head or l_high

FIX: Passengers were not updated when selecting a different setup
Modeller:
New flood select function to select all triangles by point sharing
- different from CTRL+SHIFT+LMB (select related triangles by edge)

- triangles are considered connected if they share a single point
FIX: Keep merged subobject feature was controlled by wrong option

- set axis, angle and time of rotation in modeller
- test using slider bar in vehicle editor Lights tab
Modeller:
Option to keep an empty (rotated) subobject after "merge into main"
- and break off main object into rotated subobject works as expected
- for example the following sequence of operations is now possible:
1) rotate a subobject to convenient orientation for modelling
2) merge into main but keep the empty rotated subobject
3) model and map the subobject in that position
4) break off into the rotated empty subobject
Changes in Editor D52:
Wheel object visibility:
No change in editor but game now matches the editor
- "inside covered" or "open wheel" only affect logo and lighting
- visibility of brake disc and spoke object is no longer affected
Rim and spoke objects:
Rim now gets material properties from first mapping in spoke object
Spoke object can have more than one texture page, including _ALP
- for example a chrome material can now be added as first mapping
- and in that case the rim would also use that chrome material
- no alpha sorting: transparency should only be used for overlays
Lights:
Multiple mappings per special name e.g. more than one l_head
- a second word is allowed e.g. 'l_head front' / 'l_head top'
- the second word is only to make it clearer for the mod creator
- extra names such as l_sbrk and l_tbrk are no longer needed
- reduced number of special light mapping names from 18 to 12
- mesh configurations are now fully supported by the lights
- e.g. separate mappings like 'l_head stock' and 'l_head sport'
- NOTE: maximum of 4 mappings per special name in a configuration
- NOTE: all mappings in use in a group must share a single texture
Dashboard:
Option: Show low and high beam icons simultaneously
- (shows icons for lights less than the current light switch)
Option: Show dim icons when not illuminated [default yes]
- (allows you to disable the faint image of icons that are off)
Option: Show dim segments of digital displays [default yes]
- (disable the faint non-illuminated segments of gear / speed)

We are getting near the next test patch, which will be semi-compatible (same physics and graphics, new mod options).
I've updated the change log in the first post, to bring all the updates from D to D48 into the same list.
I hope it makes sense. I feel a bit like this:

Come on guys, I'm trying to work and could do without these off topic questions.
It's a test patch. Usually I don't prepare the whole auto updater system, just to stick up a test patch. It takes far too long to do.
Please, report problems with the test patch or don't comment here.

There was a known bug that caused LFS to hang when generating AI paths for certain mods that were created incorrectly (with "Max up" wrongly set). The bug was fixed in Test Patch D45.
I don't know why a computer would need restarting. In the case of a hang, you can "End task" or "End process" using Windows Task Manager (CTRL+SHIFT+ESCAPE).

As the tougher parts of the AI were finished (for now) in D46, I was able to do another small change that had been planned for the incompatible version. The four character version of a mod's name now appears in the results table instead of "MOD". It's an imperfect system in that more than one mod may end up with the same 4-character name, but it is useful as an indication of a mod when space is tight. Of course the algorithm used in LFS was designed to be the same as the one used at LFS World, so hopefully the names are always the same!
After that, I looked back through this thread and found various issues related to AI and pit stops. There were a few reasons for AI to speed in the pit lane, miss pit stops and miss their garage when parking. Also I was able to update the pit speed limiter to be more realistic and more reliable at the same time. Fixed some rarely seen interface bugs too.
Thank you for all the testing and comments!
Changes in Test Patch D47
Interface:
Four-character mod names are shown in results table instead of MOD
FIX: /setlap command error if name coloured and number 4 chars long
FIX: Replays auto-named with special characters could appear wrong
Simulation:
Pit speed limiter now based on drive speed instead of world speed
- prevents wheelspins (e.g. at RO) pushing car over the speed limit
AI:
Avoid excessive downshifting when approaching speed limit zone
Approx 1 second safety margin entering pit lane to avoid speeding
Use speed limiter or throttle to avoid wheelspins causing speeding
Smoother transitions switching between main path and pit lane path
FIX: Some mods would brake too gently and miss the pit stop point
FIX: Some mods would overshoot their pit garage when parking

OK, the pit stop issue is definitely fixed. Thanks for the reproduction but this one is too unreliable to use as a proof of fix. I couldn't reproduce it (using default setup). I would need something like 100% reproduction method, hopefully for a single car on a short race. Then, if it didn't happen in my test version we'd know for a fact it is fixed. But I'm not asking you to keep trying it, just let me know if you happen come across one where it happens every time.
I was asking specifically about problems joining and leaving the pit lane path, but I think you are talking about ordinary corners?
If you are talking about bikes failing at corners, please state the exact bike and which config, as all the bikes I have been testing with, do not crash on any configs I know about.
Well what I originally asked about was an AI issue, but Michal's reply was about a speed limiter issue.
I'm sure the speed limiter issue is fixed but would be grateful for some testing after D47 is released.
The AI speeding may have been fixed (by other means) but without a single example to test against, it's hard to say.

Reason : clarity and typo
No problem, it's just because Flame commented on this in the test patch thread, which is somehow connected because of dashboard updates. I thought it may be worth discussing more but not on the test patch thread.
No, I think you believe that there is a separate system that is acting as a stabiliser. In fact the entire balancing mechanism and steering are lumped together into a steering model. The user sets the lean, then the steering model attempts to achieve that lean solely by adjusting the front wheel steering. It's a very challenging coding task, as you can see by the two weeks it took me to get to D45, after D44.
The solution I would really like, as mentioned before, would be to have a "physics" model (simulating gyroscopic effects) and a separate "steering" model that is applied on top of that, but that is not the case at the moment and will not be the case, certainly in the 'old' LFS physics.
As I say, quite often, I am trying to get off this test patch so I can get back to the new physics so I can release the new graphics system that everyone wants. If I don't finish it, then it can't be released.
I don't think everyone understands quite how extremely active this bike balancing needs to be, to keep the bike upright at all. Without the steering model constantly adjusting the front wheel, the bike will fall instantly. For example, if the user had direct control of the handlebars, it would be impossible to keep the bike up. The balancing code is actually adjusting the steering 2000 times per second to keep the bike upright.
At this point I will only fix serious problems. I'm not going to be working on the bikes going off road in the old tyre model, or implementing a full bike physical dynamics system at this time.
EDIT: The only system like "stabiliser" that balances the bike using external forces is the "walking" or "feet down" model that takes place up to 2 m/s (7 km/h). Above 7 km/h all balance comes from the front wheel, attempting to achieve the lean angle requested by the user input.

Thanks again for the testing and feedback.
D46 contains updates for the low speed steering, making it faster to change lean angle, while leaving the high speed steering unaffected. I hope you'll find this makes it better at low speeds.
I hope that low speed stability has not been diminished. It seemed fine on the bikes I tested.
Interestingly (for me at least) it seems that a change on the final day or two before D45 was released, allowed the high speed steering model to work fine at lower speeds than the test version I had before that. So in D46 the high speed model goes all the way down to 36 km/h before the low speed model is brought in.
Changes in D46:
Low speed steering model changes lean angle in half the time
Low speed to high speed model transition is at half the speed
- Feet down model up to 7 km/h
- Low speed model only from 7 km/h to 18 km/h
- Interpolated model from 18 km/h to 36 km/h
- High speed model only above 36 km/h
FIX: Steering glitch between feet down model and low speed model

Bike riders, please can you test the new bike steering model in D45? It's a lot more stable when changing gear and braking, also it should be better at low speeds thanks to a separate low speed model.
I'll read the other posts since D44 again and make notes to see what I can do or reply as needed. My main focus has been trying to improve this bike model which became less stable due to an improvement in D44. In this version, the underlying physics is unchanged, only the code that steers the front wheel is different. After the bikes are done, I can get back to finish the intermediate incompatible version with improved mod support, so finally I can get back to the development version and new tyre model.
This diversion onto bikes has taken a lot longer than expected, but I know there are a lot of people who enjoy the bikes and I wanted to make it more acceptable for now.
Changes in D45:
New more stable steering model for bikes:
Improved handling and braking ability
A new high speed model is used for speeds above 72 km/h
A special low speed model is used for speeds below 36 km/h
Models are interpolated between 36 and 72 km/h
AI:
Bike can now brake harder (safety margin the same as cars)
FIX: A hang generating path for a mod with "Max up" wrongly set
FIX: Downshift avoidance was too strong (sometimes needed clutch)
Interface:
A message shows the name of any mod that can't be loaded in an SPR

Thank you all for the feedback.
About bikes, I can clearly see the issues you report, not only wobbling when braking from high speed, but a lot of movement when coming off or applying the throttle, or tapping the brake a little when leaned over.
I've experimented quite a bit but haven't got any conclusive improvements yet. It seems like I can dial out any issue but doing so always causes other issues at other speeds or conditions. For example I've been able to get really nice accelerating and braking while leaned over at medium to quite high speeds, but then it's a lot worse when the bike hits a relatively small bump and seriously overreacts. The trouble is that what I call the "damping" part of steering (that tries to reduce wobbling by bringing the lean rate near zero) needs to be quite high to react quickly to certain things, but it needs to be gentle in other situations.
I also tried the early stages of a more physical model which tries to simulate gyroscopic forces and really apply steering forces to that. To separate a bike's natural handling, from forces applied by the arms. But it seems a little distant for me to produce such a genuine physical model at this time and I'd rather not do that with the old tyre physics. And a complete model would need body movement too, which isn't for now.
So in that case I'm left with the original plan to improve our semi-physical model (the bike is in physics but the steering is just doing what it needs to do to balance that bike at the required lean). I still hope to improve it, given my increased understanding learned last week, now that we have better bikes and more of a range to test it on, it seems like I should be able to improve it in some way.

But it seems a little distant for me to produce such a genuine physical model at this time and I'd rather not do that with the old tyre physics. And a complete model would need body movement too, which isn't for now.
So in that case I'm left with the original plan to improve our semi-physical model (the bike is in physics but the steering is just doing what it needs to do to balance that bike at the required lean). I still hope to improve it, given my increased understanding learned last week, now that we have better bikes and more of a range to test it on, it seems like I should be able to improve it in some way.
I understand but this is not a suggestion thread. It is only to discuss changes that have been made in this test patch.

Test Patch D44 has some more improvements including better (safer) braking and faster bikes. I've tried to deal with some of the issues that come up when bikes are allowed to go faster.
Mainly:
- improve line following by fixing a physics flaw
- taking off over bumps at high speed
- braking too hard for their ability
- unnecessary downshifts
The bikes are a fair bit faster now but there are some issues, with some bikes on some tracks. If you have problems you can turn them down to (approximately) their D43 speed by selecting OK instead of PRO.
Examples:
- Mod 'Cruiser' keeps crashing at AS4 due to wobbles at speed
- Fast bikes crash due to bumps before the South City underpass
I can't yet make LFS detect which bikes will be a problem so should go slower, or detect where fine bumps will bounce them into the air, but it's more fun to let the AI go faster so at this point I think it's better to leave it up to you to slow the bikes manually when needed.
The car AI drivers are better at staying on their line at the corners because of two changes: (1) taking account of engine braking and (2) allowing an extra safety margin when braking. In some cases they may be slightly slower but it's a reasonable price to pay for much more reliable AI across the board.
Other known issues:
- AI can sometimes stall but don't know how to restart engine.
- Some karts at some tracks can repeatedly regenerate path (waiting to reproduce).
- AI were reported as being rougher in D43. Maybe they are better now they have a braking safety margin?
- EV regen does not correctly match brake force. E.g. front and rear force arrows not equal at 50% balance.
Changes in D44:
Misc:
Improved bike physics (affects lean angle and tyre forces)
FIX: Engine brake reduction had no effect for EV but was visible
FIX: Replay OOS after a reset attempt was prevented and long wait
AI:
Bike cornering and acceleration limits increased by 25%
Bikes slow to avoid taking off over large humps in the road
AI braking prediction now takes account of engine braking
Braking prediction includes a safety margin to avoid late braking
Avoid unnecessary downshifts by looking ahead to see if needed
Reset is available even after engine switched off after long wait
FIX: Sometimes could reach a maximum speed and stop accelerating
