Yes, I know, this is a fair "shortcut" for on-road and high-speed car
simlations, but it behaves quite unrealistic when crawling over sharp
rocks with near-flat tires. Would be fun to try to implement it, though,
even if it would be slow (we'd just make it optional). I've never seen
that being done before.
