On the general topic of the 'racing' line, It is clear (as I have said in other threads) that for an overtake to happen, by definition at least one car has to move off the racing line. I do agree with Road of Bones that generally it is incumbent on the car behind to avoid contact and to make the pass safely, but if too much emphasis is placed on any contact always being the fault of the overtaker, then pretty soon the only place drivers will feel safe attempting to pass will be on the DRS straight.
I do also think that the supreme efficiency of modern brakes, and the resulting reduction in braking distances, has had an effect (maybe as much as or even more than aerodynamics) on the ability to overtake cleanly by getting sufficiently ahead of the other car before the turn-in point, by outbraking them. I have long thought that the brakes were an area that the OWG for instance should have been looking at.
