If nothing there are two objective criteria to judge a physics model, whether it's correct and whether it's updated often enough for the speed the simulated car will reach. 800Hz for example should be enough to "feel" a road modeled with 25cm granularity at 360km/h (=100m/s) as (100m/s)/0.25m=400Hz and we must multiply by 2 for the sampling theorems.

Add a potato to the mix.

That's around 12cm, so it would need 1600Hz!!!

 

But it's not moving!!

Seriously now, I thought you were kidding.  If you are not, then I don't understand quite a lot of things on your post.  For starters how m/s /m results in Hz?  Oh wait I got taht!!
