I'd be interested to see what a LEO would have to say. Quick, someone call hedo.
The guy blasting through on the left turn is clearly in the wrong, but someone so obliviously unaware of it as to drive aggressively, at speed, square into the side of it, having been so clueless of it even entering his path of travel, well, there's an argument to be had there that had be been paying the slightest bit of attention he'd have never got as close to the collision as he actually did. I'm sure a LEO would have looked at the footage and said "You could have avoided that, dumbass". Whether charges would be possible, hard to say.
At one point I actually asked myself if he WAS actually aware of the van and intentionally accelerated towards it for dramatic effect...you know, being yet another YouTube hero and all.
FWIW, if you look at his videos, this is the same guy that crashed broadside into a turning car a while back, I remember someone posting the video here - he was busy scolding a taxi who creeped into his way at an intersection, and once again was unaware of a car turning into his path of travel. Again, car was at fault ultimately, but had he maintained situational awareness instead of taking his focus off the road at something totally unnecessary he would have avoided that accident too.
