Set 0% throttle to not regen and coast around the corners when you can. The latter fits well with "good" driving, traction pie habits anyway, you *shouldn't* be braking or accelerating much while turning and saving your traction for changing direction.

What do you mean "slip mode"? If A motor like the one in your car unsyncs from its rotating magnetic field, it looses ALL torque. It might work fine for an induction motor, but definitely not for a BPMSM.
Also, there are plenty of "good" drivers who would disagree with you about when to brake or accelerate. You'll find them on most racecourses.
