everyday driving I use my right foot. but for racing you need to use both feet, especially while driving the top end

And my street car is a clutch/manual transmission, so I need the left foot for the clutch!

Even in the staging lanes, footbrake at the tree, return road, I use my left foot on the brake pedal. Before I started doing this, a couple times it took too long to get my right foot off the gas and onto the brake before the finish line went by (and therefore didn't close up the gap at the very end). Things go by fast at 140+ mph.
