i think he pulled out because it was gonna be heads up, on a drag the more torque and hp wins, no real driving skill unless your shifting, you may have had your hands full doing a track like race, takes a lot more skill, knowing when to brake, how much to brake, then gas how much to turn the wheel, with the size of the gp compared to the others, you might have spun out and gotten hurt, so good thing on not doing the track run, but i think it would have been a good test of driving skill
