The 'one move' rule clarified

[ArrowsFA1]

Michael got pretty close to the one car width with Rubens a while back , and people got pretty excited .
Mind you , it wasn't on the inside , into a corner .

Good point. It wasn't on the approach to the corner so do we assume it's perfectly ok to squeeze people into a wall, or onto the grass, as long as it's not on the approach to the corner?

Where does the approach to the corner begin ?

Where does the approach to the corner begin ?

The exit of the previous corner
The braking zone for the corner in question

[Bagwan]

What if this all involves a chicane ?
You'd have to allow room on the outside , because that's the approach to the inside of the next ?

Well you just have to time your one move right for it to be legit but there's Article 20.4 (previously 20.3):

"Manoeuvres liable to hinder other drivers, such as deliberate crowding of a car beyond the edge of the track or any other abnormal change of direction, are not permitted."

Makes you wonder why its written in the first place...
