The wider the rectangle, the more stable the car is.

The lower the center of gravity, the more stable the car is.

And, yeah: you NEED anti-sway bars.

I'm working on an update to the carworld demo, which breaks 
the car simulation into its own file (makes it easier to see 
what's going on :-). It also fixes some bugs. Stay tuned 
(famous last words). The previous version is available at:
