Re: System stability and changing gears in TORCS.

Hi

Yes, if the car damage is more than 10000 damage points it gets removed 
from the race with a "virtual crane" (lift off the track, move to the 
side, let down).

Damage is done in collision.cpp, so you can comment it out/modify it there.

Best regards

Bernhard
