I agree, the lateral grip drop off past peak is quite sudden, especially when combined with some longitudinal slip like on hard acceleration on low speed. This is also one of the reasons I'm slow, low 1:08s on Palm Beach, almost 8% off the pace. That's bad even for my skill level. I'm mostly driving by feel and not using conscious brake markers or turn-in points etc. if I can get away with it. As I'm not trying to memorize as much, on throttle I'm tentative, I don't want to get near that cliff as recovering is tricky. Spazzy 'sawing' action is close how I would describe it too. When I'm lapping offline I don't care about lap times that much, so the driving can be fun. But when going online you want to be competitive and the limit behavior becomes problem if you want to be somewhat fast.
