Are you trying to say that if a driver gets even slightly alongside, under whatever circumstance, the driver ahead is no longer allowed to take the racing line?
What I am saying is that if a driver is ahead but overlapping, he does not have the right to be on the racing line, if while doing so it crowds the other car off the track.
If for example this racing line goes diagonally across a straight (like start-finish in China), the driver can not continue over on the racing line while the other car is outside.
Hopefully this image is understandable. A shows an illegal move, B the legal option. It just happens that in the cases in Bahrain, it was through corners, rather than straights, but the racing line moving across the track is the same, and the crowding was there.
