In normal racing the one who's behind has to consider that
- the one infront may be braking earlier because he's new to the track
- his braking is much less efficient when in the slipstream of the car infront
- that for each car in a corner he has to brake a few metres earlier to the normal "hotlap brakepoint"


He can brake as early as he likes, drive as slow as he likes, take an inefficient line, all three (keeping within the rules of course). Unless he is under blue flag conditions he doesn't need to worry about how fast the car behind him is, he can drive his own race.
