You're right to condemn it T - thrilling without doubt, but it's the sort of behaviour that gets bikers a bad name and puts many others at risk. [smiley=thumbdown.gif]
Shortly after I'd transferred over, my first call to a fatal RTA, as a constable, involved a rider + passenger and a parked (broken down) vehicle.
Speed was the sole factor in the collision, as a result of which the rider was killed instantly (as far as can be ascertained) when their head struck the kerb on the opposite side of the road after being thrown off, the passenger was more fortunate as they survived - albeit with serious, life changing injuries.
The utter emotional implosion of that rider's mother when I broke the news to her and the look of complete devastation on the father's face when he identified his child's body remain in my mind to this day.
Speed in itself isn't a killer; it's the irresponsible use of it in inappropriate circumstances that makes it bite. Road users who display the level of irresponsibility shown in the video clip should be jailed immediately and have their vehicles impounded.
