When they set a DRS activation zone, could the drivers just keep pressing the DRS button BEFORE the zone, then have it snap open (saving a hundredth/tenth/whatever) as soon as they reach the activation zone?
Also, is there an "end" to the activation zone? so, let's say (numbers exaggerated for scenario purposes)
Let's say, a Hispania has a 150m braking zone for Turn 14, while a Red Bull has a 120 meter braking zone. Does this mean that Red Bull would have a longer DRS zone, as they can keep the DRS on for longer?
