I am not sure that rear wheel steering is ineffective as you indicate below.
That car used a couple of military jet engines with full afterburners, if I
recall correctly. If the thrust angle is/was off just a smidgen then
steering on either end of the car was likely to have problems. And while
rear steering may be problematic, it should function just as well as front
steer when the driver understands what he/she is doing. Skid control and
turning are counter intuitive and that takes some getting used to.  How much
was full lock on the Thrust car? 1 degree? 2 or even 5? So saying lock to
lock is hardly much of a factor because the missile is going straight where
the engines point it and hardly any amount of wheel turn will correct it. It
simply heads off in the direction the engines push it and drags the wheels,
would have happened with front steer also.
