I had simmilar problem when I was trying to play LFS on my old Celeron 333. During the start and while several cars were driving nearby I was making about 1/2 fps. Only when I was temporarily alone the framerate was jumping to enormous 10 fps

Give us your computer specification. I suppose your CPU is not good enough.

Actually the real one - Michael Shumacher did two wheel driving after hitting other car tyre in 1994.
