For reference, I've heard it said that the Carmageddon series did 25 Hz 
physics.

There are many ways to skin a cat, though.

200 kph is about 55 meters per second, which means about 0.5 meters per 
step at 100 Hz. You can "detect bumps" by just sweeping a capsule along 
the movement range of the wheel ball (from last step to current step) 
and creating contacts based on what this sweep returns, although most 
wheels will detect most noticeable bumps at those resolutions without
this sweep.

Cheers,
