Honda Prelude had it way back in the late '80's.  Mechanical linkage - for the first few degrees of steering input, the rear wheels turned in the same direction as the fronts, but beyond that, they reversed and turned against the fronts, hence a very tight turning circle at low speed.  Turning with the fronts with small steering input was supposed to help stabilize lane changes, as I understood it.  I thought it was clever but have no idea how well it held up.  Can't remember the last time I saw one of these cars.  There was a "4WS" emblem at the base of the B pillar, right behind the door glass.

FWIW, YMMV, yadda yadda....

Curious what everyone thinks of rear wheel steering in general and if
anyone has ever experienced it themselves?

Right now only the F12 tdf and 812 Superfast have it I think? Not sure if
the base F12 has it.

Now Lamborghini followed suit and put it on the Aventador S.

Was one thing when a handful of cars back in the day came with it....300ZX
Turbo I think. But now when Ferrari adopts, it's time to pay attention!

It sounds like a nice way to improve turn in but wonder how it affects
vehicle dynamics going into oversteer and the like?

The purist in me is cautious......however, I think this over AWD any day. :)
