Any other ideas? What do those guys like Mythbusters do for remote
control full size cars?

My tendency would be to use hydraulics. Small control voltages from an RC
receiver could drive (or be amplified to drive) hydraulic valves.

With a bit of planning it could be made proportional, by driving a power
steering valve with a beefy 1/8-scale servo.

You would probably still want to put a position sensor on your actual
steering angle, and steer that in closed loop -- but this sort of thing
should work quite well.

Where does one find a "power steering valve" -- is this a stock
hydraulic supply house item?

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" gives you just what it says.
