So that's my open-minded question. There is no fundamental problem getting electric motors to apply as much force as desired - even, as with the rail gun, far more than the car's structure could withstand, let alone a human body. But how do you get tires to apply enough force to the road to accelerate at that rate, instead of just sitting there burning rubber?

They're using slicks, from what I can tell, and they're using warmer blankets to keep them at the right temperature and stickiness.
After that, it's all about knowing how much grip they have and adjusting the controller accordingly.
And the ice thing, that can be dealt with via an inertial/GPS traction control system. It still won't accelerate quickly, but you can fine-tune wheel acceleration rates so that you're not needlessly spinning them up.
