Actually, the AP1's reputation for being a handful is pretty well-deserved due to rear toe change with bump. The AP1 suspension geometry causes the rears to toe in in compression and toe outward in extension, a gimmick that has been tried before (FC RX-7, NSX). The idea is that you get great initial turn-in response, then as the car heels over in a turn the outside rear toes in and the inside rear toes out, giving more understeer. Even if there were no real downside, it makes the car behave nonlinearly, with initial oversteer followed by roughly neutral handling.

But if you should happen to LIFT while cornering, the rear end goes up and the outside rear toes OUT, giving a double-dose of increased OVERsteer (dose one from unloading the rear tires, dose two from the outside rear toeing OUTward).

So, when the uninitiated driver starts to feel the back end get a little squirrelly and gets off the gas, the car really really REALLY wants to come around, and often does.

So, yeah, driver failure, but the stupid and unnecessary designed-in rear toe shenanigans make the car particularly hairy for drivers who do not have experience driving at the limits of adhesion.
