I have read that some form of four-wheel steering is a feature on a number of production cars, but I haven't been able to find details of those systems. I'm particularly interested in whether four-wheel steering has ever been applied for non-rotational, crab-like lane-change maneuvers: I.e., instead of having the rear wheels turn in the opposite direction of the front wheels to increase rotation, can any systems turn the rear wheels in the same direction as the front for emergency lane changes? I imagine the performance advantages of not introducing a rotational moment in the body at high spee

I know of at least 1 case where that was true. From Autoweek Honda’s first 4WS system, launched in April 1987 on the Prelude, was all mechanical, using a shaft to connect the front-steering rack to a slider operating the rear tie rods. A planetary gearbox determined rear-steering degree based on steering-wheel angle. At small angles, the rear wheels would steer up to 1.5 degrees in phase with the fronts, but at larger angles (more than 246 degrees of steering rotation), the rear wheels would steer up to 5.3 degrees opposite the fronts, trimming the turning radius about 10 percent. Edit: Actually, the article cites several examples.
