In LFS you can crash a barrier, fly high, crash to the ground, have a lot of damage and you still can drive the car at near racing speeds...
In all simulators (and real life) you will cant drive or just move the car...
Why dont drive to pits, repair and go? If you go to pits, its like you restarted the race (for you) and starting from pits, if you repair, you will be far from the leaders but you can catch up...
