Yes, actually. Mind you, I really wouldn't want it to do so while toting me around.
That said, if the car were to loose traction for whatever reason, I would expect said autonomous vehicle to recognize what was happening and handle the situation as well as possible. If drifting was beyond it's capabilities, then it should only be in control of a vehicles that go no more than 5mph, limited to private property, and only operates under strict human supervision. :P
