saw an SL w/ a drive by wire system on Speedvision
i thought it was fantastic! i don't know how you make a tight U-turn w/ it though? w/ a wheel, you can go hand over hand but w/ the joystick, how?
it ended up by saying that it was illegal b/c there was no backup system.
I think the steering rate is proportional to the force applied to the stick. The harder you push on the stick, the more the wheels will turn.
