I watched this a couple of days ago on another website and first thing I thought was "WHAT A DICK" to fast and doing what you should never do trying to keep up with his mate, ride at your own speed not someone else's, there was a pothole but nothing major about it and truth be told he was lucky the LORRYIST? didn't squash him flat, I did wonder about the final moments where he put's his foot down just before he bin's it, if perhaps he might be a new rider rather than a total prick, not sure about that but either way his own fault and glad the driver had a camera on his truck, that's why I have one on the bike.
PS did you see the comment from ANGELA below the video? What a cow, only she it seems is allowed to drive on the roads and only she is good enough to have an opinion on how to ride, F++K me I do not want to meet her out on the roads.
