- The animation community leads in this area. See Zeltzer's paper in
- "Making them Move", (Morgan Kauffman, 1991), and especially watch
- the car sequence in the accompanying video.

- Vehicle dynamics is rather well understood. The basic work
- was done about two decades ago at Cornell Aeronautical Laboratory
- (now CALSPAN). There's a great story about how the person who did
- that work, annoyed by people questioning whether he could really
- predict vehicle dynamics in extreme situations, teamed up with an
- auto thrill show to design a never-before-done stunt, a 360 degree
- roll in the air. Worked the first time. Appeared in a James Bond
- movie.
