The track was at fault, agreed. Not the driver though.
I've watched this incident over and over because I simply don't agree with the ban or the way this has been dealt with in the media.
I'm sorry, but you've obviously not driven a single-seat racing car if you think that. It's nearly impossible to know everything going on around you in situations like that, and both drivers did exactly what I'd have expected them to do. The driver behind went for a gap and the driver in front tried to close the door. Both of those moves are legitimate racing moves. It just so happened that the driver behind took his chance at the wrong time for the driver in front. The 'conventional' line to take would have been to try the outside line, but since it was the final corner, he went inside instead and because the timing was off the cars had a coming together. It's funny really, the commentator called it live during the race before any of the reaction kicked off.
This incident was no more unusual than Lewis/Nico, except that the track wasn't suitable for that sort of racing.
