[ODE] Not cylinders, but discs?

Cylinders aren't yet fully working. From what I understand, the main
reason to get cylinders is for car wheels that don't "stick out" on the
side of the car, with oil drum objects being a distant second.
Thinking about what you'll get out of car wheels, and how rays for
wheels work just fine, wouldn't it be feasible to do an infinitely thin
disc primitive? The hardest primitive to test against is usually
trimesh, but disc-triangle is just a line segment-circle in the plane of
the disc (assuming early rejection cases based on the disc plane have
You'd model car wheels as a disc where the outer edge of your tires
would be; the inner edge, or even rolling surface, just aren't as
important for simulation.
I certainly don't have time to write this primitive, but is it something
to think about?
