Sidecar rigs are a whole new ball of wax- I do not know how to drive one, but from the little I understand, as long as the three wheels are on the ground, they steer like a car(no countersteer). And as soon as the car "flies", they revert to countersteering. As in most thing motorcycling, Dave Hough (author of profiecent motorcycling ) seems to be a leading teacher.
The Urals apparently have gotten a whole lot better as the Russians have learned to keep up with western demands for reliability.
