That assumes you're modeling the bumps and dips in the roads you drive on
with similar accuracy.
Seems to me that if you tweak it until it seems about right, then tweaking
a parameter of the simulated car by 10% should give you a pretty good idea
of how the handling will change in reality if you tweak a parameter on the
car by 10%.
