How old are you? I seems you don't have a great knowledge of drag racing,try running dead on a 9.90 index @160 mph without electronics, consistantly.

I think that is his point. It is very difficult. Those that can, foot brake. Those that can't, use the electronic crutch.
I have been a foot brake racer since 1958, and will never use a "box".
