[ODE] Cheap Car simulation

[Sergio Valverde]

Adam,

If you don't need very accurate results you can always try to reduce the
number of steps in the iterative solver (aka stepfast). Hopefully, the
system will converge to a quick-and-dirty solution that may be just ok for
your purposes.

True, but on my pc (Athlon 2400XP), I can *just* scrape 60fps with about
40-50 cars, before any pileups take place. I really need a cheaper way of
simulating them. Accuracy isn't a huge issue here, as long as they're
roughly car-like in their handling :) I'm sure that stripping out the four
hinge2 joints would mean for a big speed boost.
