Since you have maximum traction when there's no wheelspin, maybe you could devise a system that compared the rotation of the front and rear wheels and slightly backed off the throttle if it detected any slipping, checked again and backed off if... etc. If it detected no slipping and your foot still hard down on the pedal it could nudge the throttle up again until wheelspin started again. Maybe the lag of the throttle action would make this unrealistic but until it was banned (and after too, if the rumours are correct) Formula One reacers used something similar (but no doubt much more complex) to great effect at the start of races. .
