I do believe the contact probably slowed Hamilton down further and even with that further slow down, he still went wide probably with half of his car out of the track. It was definitely not a very good line to take that’s why leclerc ended up passing him.
So I do believe Hamilton will likely fly off the track without Max’s rear wheel’s help.
Of course it’s also possible that the legendary trail braker could continue to slow during the turn and therefore able to remain on track… the contact simply interrupted this braking during the turn…
