Thoughts?

Because the throttle is commanding torque is there a possibility of the spinning wheel RPM increasing to dangerous levels as the controller tries to bring the torque up to the requested level? Not easily achieved on a slipping/spinning wheel. I am thinking of one wheel on ice sort of situation. Even in a single motor situation on ice would the controller keep the rpm under control?
This is just a theoretical question for me, living in Australia the only ice i ever see is in my drink.
