Hello,

I have a few questions regarding the behavior of LFS cars.
Why is it possible to crash into a wall with 200 km/h (124 mph) and still continue to drive? I hope LFS team will make this more realistic.
When accelerating in a higher gear than appropriate, LFS automatically starts from 3000 rpm (in XF GTI) or even 4000 rpm (BMW FB02).
Even with manual gearbox, thats what is annoying me. Why dont they let start the gears at idle speed, or let it stall if gear is too high?
After having done this a few times, the car doesn't accelerate anymore, only revs up. Probably the gearbox broke? But when I did this to a real (old) car,
it didn't break that early, maybe it would have broken after 50 times, but not after 3 tries, so is this realistic?
(Don't worry, I don't usually treat real cars that bad...)
Are these race cars clutchs more sensitive than normal cars?
Why doesn't the car stall when started in any other gear than neutral?

Thanks and regards,
XCX

You probably have auto-clutch enabled, keeping the car from stalling and baking the clutch as you attempt to start in a high gear.

1. Damage model incomplete.
2. Auto clutch or manual clutch?
3. Cars don't stall if there gears are too high - the wheels going round means the engines carries on. It might get a bit horrible though, kangarooing down the road.
4. You melted the clutch. Thus I'm guessing you are using auto clutch (see 2.)
5. Race car clutches are more sensitive as material is removed for inertia reasons, giving less heat capacity.
6. Because auto clutch it pressing the clutch for you. I could start any car I have owned in any gear. Some have gear-ignition cutouts to stop Americans driving into shops on the starter motor.

Thanks, didn't know about auto-clutch. Now it's working almost as it should. I just wonder why the car doesn't jump forward a bit when started in first gear?

Maybe you're just better starting a car in LFS than in Real Life?

I think he meant jumping it on the starter motor in 1st
It does jump if your ratios are somewhat realistic, but neither the ignition system nor the starter motor are implemented properly (that is, physically accurate), so all the starter motor does is apply a predefined amount of force (torque) to the engine (which itself is only a minimalistic model) once per virtual key rotation.

Yes I meant starting it the wrong way, thanks for the info.
I don't own a wheel with clutch, like Logitech G25 for example, so I have questions about that: If you release the clutch pedal too fast, does the car jerk like in real? Is the clutch just like "gear engaged, or not engaged" (on / off) or is there a big sliding area between it, like in a real car?

The clutch behavior is somewhat closer to reality that the starter, but it is far from being perfect. If you press F8 to see the G-forces affecting the car, you will see a sudden short "boost" of longitudinal force if you release the clutch too fast. Also if you keep the clutch half-depressed while driving, it will overheat really fast. But this modelling is far from finished and it also models racing clutch, which behaves kind of differently.

BTW, why don't you just try all of these things yourself rather than asking us if they are present or not and discuss your findings with us?

Because he doesn't have a clutch pedal

The clutch is analog, so there is that "sliding" area as you call it.
If you release the clutch very quickly with low revs (and your gears are short enough), the car will "stutter" a bit, the revs will jump up and down a little (almost like in a real car) and then it'll go. If your gears are too long, you'll just stall. It's not as well made as in RBR, but it's quite OK.
