A method I have been experimenting with is setting up the steering system exactly ala
the Lego Technics cars, i.e. with one beam fixed to the chassis and three other beams
forming a rectangle, the steering column moving the beam parallel to that attached to
the chassis and the wheels connected to the side beams, in which case the effect of
steering is a contact constraint on the top surface of the "parallel to fixed" beam.
With the 0.035/CVS and above API you can even chuck in a feedback buffer to get an
accurate backward force for that sort of steering wheel.

Has anyone else tried anything like this?
