I think some drivers rely on breaking to enter a corner late then hit the throttle to power thru and exit , I've seen others set up corners rolling , to have the best line and throttle control exiting .. I think driving with breaks at every corner or turn would give you longer laps time's and asking them self's why are my lap time's so high ... Alot depends on track conditions and layout .. most Importantly driving style .. I find myself throttle driving and breaking only when needed ...
