But i guess it might be applicable only for past, when brakes were so bad that couldn't be much relied upon anyway. Unless it's straight like eg. dragstrip, one cannot lap faster without using brakes. There are other ways to bleed speed too, eg. sliding sideways, but they'll make one's lap speed worse aswell vs proper driving. And even in rally driving on gravel or ice sliding everywhere stages, brakes are used for mass transfer / turning a lot, not just for primary function. If one drives fast enough, one needs to slow down enough .. and at right point, right amount and in right fashion.
