I was just thinking about this and considering what pushing a rear

ISTR that Thrust SSC was rear-steer.

It was, and when teh engineers proposed it as teh solution to various
problems it was mightily poo-pooed. It'll never work, inherently
unstable, blaah blaah. In fact, read on in the thread for the sort of
comments heaped on teh rear-steer proposal.

They built a steering prototype by taking a mini, locking teh front
wheels straight, detaching teh back axle and substituting a long pylon
with steering wheels on teh back, such that the geometry was a
scaled-down version of the Thrust proposal.

Apparently it steered beautifully, no problem at all, as long all teh
linkages were fully 100% ok and there was no slop in anything.
