Overdrive
I would like it so that the stock cars have overdrive transmissions (as an option) because sometimes I just wanna cruise around a track and I don't like doing 4000 rpm (in top gear) when going about 100 km/h.

This would be more realistic.
Well you can always shift into top gear and feather the gas?

Although proper automatic simulation would be nice (overdrive, kickdown, variable shift timing)

Well run longer gearing then. I think the gear ratio range in LFS is plenty long enough to be having overdrive gears (although I've never checked)
I want automatic tranmission simulations in LFS for two reasons.

The first - so people who don't bother to shift manually (heel toe and all that includes) get the dis-advantage they so rightly deserve for being lazy.

The second - racing automatic cars would prove an interesting challenge in say an all American V8 (think dodge challenger) racers cup. I know they're terrible cars, but they look like a lot of fun, and as long as everyone has terrible cars, the race is still fair and interesting!

You see that's the point. I don't want to have to change the gear ratios to get lower revvs in top gear. I want it to be like that in stock configurations, meaning original gear ratios. That would just be more realistic.

No one who drives on the highway (100km/h) in a modern car exceeds 2500 rpm in top gear. So driving on the highway in top gear doing 4000 rpm is unrealistic.

Agree?
So youre too lazy to adjust your gears when you have the option?

You have to drive the ridiculously short geared cars we have in Brazil then
It's common to hit 4000rpm in a highway, and these cars are very very noisy
My moms Toyota Corolla is a 3speed auto. It screams at highway speed, and redlines at 120kph Try listening to that for hours on end.

The 106GTi sits at near 5000rpm when cruising on the motorway. It's quite typical for European cars to not have a very tall top gear, unlike some American cars. Seeing as the cars in LFS resemble European cars, the default gearing makes sense. Seeing as the gear ratios are all individually adjustable in any of your custom setups, I don't see the point of the improvement suggestion.
added to which i've never seen an overdrive option on anything since five speed gearboxes became comon place.

if you want to model a four speed with overdrive on top then copy the nissn stanza approach, set your gearing on the first four and then bang on a high geared fifth. however id suggest you dont go the whole stanza approach as they made a four speed version with a top gear which was similar to most other cars fifth and then on the five speed versions, rather than lower the fourth and fit a fifth that was slightly higher than the four speeds top, they left the fourth ggear the same and then fitted an even higher fifth (can't remember the figure but it was circa 30mph per 1000 rpm which is fine on a big US v8 but not on a late 70's carb fed, 8v 1600 ) the result was a car which autocar actually failed to record a 50 to 70 acceleration time on a perfectly flat straight, in fact most magazines actually found it hard to get the car to accelerate in fifth from any speed and top speed in fourth was considerably higher than in fifth
FWIW, overdrive simply means top gear is less than 1:1 ratio.

It must be horrible running around at 5000 rpm in top gear (from one of the comments above.) But then again, I guess it's more common over here to be driving 20-40 miles at 60 mph without needing to stop, unlike smaller, more populated areas where you have to stop every block.

A quick run to the store for me is 39 miles, and I have to stop twice. Once at a stopsign and once at a traffic light. Other than those two stops, it's time to open her up .

.

once again proving that we are seperated by a common language

over here overdrive was a seperate gearbox fitted to output shaft of gearbox with two ratios and (usually) electrically switched either by a dash switch or rather neatly by a switch inset on the gear knob which is great for kidding little boys that its the ejector seat switch like james bond's aston

re the ratio being less than 1:1, most gearboxes over here run a 1 :1 ratio in fourth so if a five speed the fifth is usually an "overdrive" ratio. however given that there are many high reving engines theese days its not uncommon for the ratio to still equal a fairly low mph / 1000 rpm after the final drive and wheel size have had their effect
going back to the original suggestion, if its common on your side of atlantic to mean a ratio of less than 1:1 when refering to overdrive, tehn all thats being suggested is that the default gear ratio settings need altering which has to be the most pointless idea ever given that all you have to do is adjust it yourself and since you want it as an option then its even more pointless as the option is already there in the adjustment

I hit just over 6k rpm in 5th gear in my miata (1.8l 4.1 final drive ratio) on the french highway, talk about noise
Psht, my M30 can do 95 MPH on the highway at about 2800 RPM

Gotta love that gearing hehe.

Pffft, my old truck could do 45 mph at 1400 rpm before it started to uncontrollably shake rattle and roll off the road

Officer: Do you know why I pulled you over?

Me: Er, no sir, I'm sure I wasn't speeding, was I?

Officer: No, I picked up your bumper about a half mile down the road
there and wanted to give it back to you.
