100% ?
Really?
Personally i would've just moved to the right, out of his path, with a couple of blasts of the air horn for good measure.
Yes, 100%
When someone links to a video like that, I tend to watch it thinking "I'm on my bike, what's happening and what would I do?"
Even with the fore-knowledge that *something* was going to happen, unless I was prepared with my thumb on the horn button or I'm set up to manoeuvre to the the right (and, not boasting, just putting these in as facts, I have fast reactions and I've done Advanced training) I think I may well have been caught out like him simply because it was *not* something I would expect.
The driver, on the other hand *should* have expected that there could be on-coming traffic, especially because he's turning into the side road at too great a speed to complete the manoeuvre without crossing the centre line.
The IAM's advice in such situations is that it is ok to cross the centre *provided* it's done as part of a properly thought out riding/ driving plan and with careful observation, plus, of course, the standard advice of "Always be sure you can stop in the distance you can see is clear" which obviously the driver did not do.
