For the record I don't agree with that analysis. At the speed he took the first corner (he's way faster than all the other riders before him), even by taking the racing line there's no way he would've had time to slow down coming into the second corner.
I think the point the guy who did that video makes, is you only see him coming out of the corner, you don't and can't see what interference has happened to the racing line in the previous corner approach and apex. These are close corners which are inextricably linked - ie being forced off the right line in the first makes a correct line in the second impossible.
Either way, we see a bunch of professional cyclists mixing it with cars on a series of very dangerous bends - it's hard to imagine those cars making it easier, very easy to imagine them making it much ha
