Should anything contact the most forward rear tyre at this instant causes a snap roll, even if the driver induces corrective steering it will matter not, the car is bluntly 'out of control'.
If one is lucky, the car will fully invert to traveling backwards, its most stable condition.

because I dont think there is any hope that the center of pressure or center of resistance is going to be anywhere near aft of the the CG, where it needs to be for stability.

And how will it ever be stable in reverse when the Ackermann effect is bass ackwards?

I think the outrageous safety record of this car speaks for itself. I know these cars are still popular to this day, and I have owned a few myself. Im quite used to the arguments that somehow the data is wrong and these are cheap to run well 'engineered' cars. But a car that will kill you has no saving graces, its just lethal and unnecessary.
