Big feet and small pedals don't help a lot. I have size 12 and the pedals are not especially good for me. Guys with big feet generally have to use the side of the foot which makes it difficult to threshold brake accurately. ABS sort of helps, but I'm a better judge of traction than ABS on dry pavement (it is pretty handy on wet pavement or unfamiliar/mixed surfaces).
I've seen videos of the really fast guys, and they are generally not very big to start with, but they typically have enough room to put the full ball of the foot on the brake, and can stab the throttle with their heels. Something to keep in mind, they are not usually using super exacting throttle control to match revs, they are spiking the rpm and catching the clutch on the drop. It's OK to be a little high, but it's really bad to be a little low, especially if you are sliding around (as you should be if you are really going fast).
All this would be a whole lot easier if cars had controls like motorcycles. Rev matching with your hand on the throttle and your feet on the brakes is dead simple. So is clutchless upshifting.
