That's an average acceleration around 2g. This seems beyond the limits of tires and friction. Do aerodynamic down forces kick in fast enough to make more force usable against the road at these relatively low speeds? Do the tires have more than static friction going for them (say, fine scale interlocking with the pavement)?
Drag racers can do 3gs, but that's at higher average speed.
