Having watched the full video, I think the original reporting is, shall we say, somewhat hyperbolic, words like "horror footage", "maniac" and "lethal" really aren't justified.
Yes, he does stupid undertakes and in a couple of places he's much travelling much too fast and too close to vehicles in blind spots where he'd be in serious trouble if someone else made a manoeuvre, but the impression given in the report isn't really borne out by the evidence.
I'm not agreeing with what he did, naturally, it was stupid and his excuses that "he was in total control at all times" and insisting his bike was built for speed don't really wash, but I've seen much more dangerous behaviour (eg texting on mobiles whilst driving) that would just get you a slap on the wrist with an insignificant fine and three points when, IMO, they should be treated much more seriously.
And, of course, when a biker does something stupid, he's mostly only really putting himself in danger, unlike someone in a couple of tonnes of car...
