People start to brake when they see trouble ahead - At this point, due to that pesky physics thing, it's already too late - You cannot decelerate fast enough - delta V + x is your car (due to reaction time) and delta V is the car in front. Also the decreasing speed curves intersect even if you do brake at exactly the same moment.
So, you have to leave a gap which compensates for those two factors. However, to maintain that gap, you have to brake early, leading to tailgaters getting rather a shock.
There's no way around this, really. Mixed skill racing is a difficult thing.
There also seems to be some misunderstanding of what "soft clipping" actually refers to.
Hard clipping can be represented in the worst case as a sound looking like:
__ __ __ __ _ __ __ __
Note that the transitions are vertical. This causes a large amount of additional high frequency 'transition' noise in itsself - the speakers literally stop with a bang. Also, it causes reverberations in the speaker cone itsself. In the worst case, this can destroy speakers.
Soft clipping makes the above picture look like:
_ _ _ _ _/ \_/ \_/ \_/
Which is much less hard on the speakers and creates less distortion, through 'curving' the top and bottom of the digital signal slightly - The actual value used is usually 1-2 bits of resolution, so has little impact on the actual sound.
The ear is an analog system, with (effectively) a inverse log (however you would describe it) response to sound pressures at different frequencies. Therefore, the 'signal' recieved by the brain has very little differentiation between "loud" and "very loud" as compared to "quiet" and "normal".
Very loud is mostly not heard, but felt throughout the body.
Clipping is an artifact of representing an analog (boundless) signal in a digitally limited space. This obviously doesn't apply in a biological system except in the most extreme cases.
I'm sure you already know this, but that's not quite the point of error reporting. Iff your application is signed (can't be self-signed, actually needs a trusted cert), you (as the application developer) can get much fuller detail than is provided on-screen to the user.
Part of the issue is I believe also related to the wheel used. In a 'real life' situation, the front wheels will tend to track the direction of the slide - This can be a quite violent action.
In LFS, the wheel is limited in the speed it can actually turn due to forces that are exerted in-game.
Might be an idea to check how much this actually affects things by setting a really small steering angle - Although this may be somewhat hard to control / quantify
Drafting was modelled incorrectly before patch S. It has been reduced since then to be more in-line with reality. You need to be much closer to the car in front to get any effect.
Calling people names and generally acting up on a forum is _not_ the way to get good, reasoned responses. Please, attempt to be civil.
You'll likely fracture a joint at another place in the pipe. These things are designed to sit for years and _never move_. Not to have people hit on them in random ways.
You've already probably got this fixed, however:
As has been suggested already, cut out the offending section (A small wheel based pipe cutter is best for this) and replace it. If you're soldering (honestly, this is the easiest option) remember to get all the water you can out of as long a section of pipe as you can. A thin tube and a wet / dry vac works wonders for this.
Use pre-soldered straight couplers. Sand the ends of the tube until it's clean copper (Wire wool works best for this), apply flux to the pipe (make sure it's water soluble flux if this is your drinking water supply) place the coupler over the pipe and the new section of pipe. Be sure you've measured everything up beforehand, and pre-assembled the other side of the stopcock. You need to then "gently force" the pipes into an assembled position. Don't yank it - That way lies employing a professional to fix what's now causing the nice fountain over your wife's kitchen floor.
Once everything's in place, just heat the joint until you see solder (very slightly) showing on the ends of the coupler. Make sure both sides of the joint are molten. Don't heat the copper too much, however - Red is bad
Once the joint is done, let it cool slowly. Don't turn the water on until you can touch it comfortably is a good guideline. This lets the joint be much less brittle than if you were to suddenly quench it.
You don't need a big torch to do this job - Standard propane works well, as long as the pipe has no water near it. You may find a "soldering mat" useful. This stops the torch flame from burning anything around the joint that you might care about. All of the bits you need are at B&Q, or any other home maintanance type store.
Some cats also are not intimidated by torches. Be careful
Don't be tempted to use plastic pipe to do this repair - Yes, it's much easier, however, you loose a major portion of your equipotential wiring in your house (Earth wiring, in common parlance). An earth strap would have to be _very_ substantial to fix this. And I'm pretty sure it would violate the IEEE wiring rules.
If in doubt, hire a professional - If everything goes pear-shaped, they (hopefully) have insurance to cover damages.
