Surprised that people are trying to defend the driver. Plain and simple - he drove completely across a lane of traffic without checking that it was safe. The onus is upon the person doing the manoeuvre to check that it's safe to do so.
Yes the motorcyclist is going fast - but they've left enough space between themselves and the queuing traffic to reasonably expect safe passage. As long as they're within the speed limit.
Judging from the way this guy drove, the motorcyclist could have been going at half the speed and the guy would still have swung out without checking first.
Don't take no chances with people like this. Lock the windows and drive away. If they follow you, call the police and drive into the nearest garage, blasting the horn. What's the betting they were filming the car so they could use forged plates on another, stolen vehicle? Not that? So what other reason would they have to film? It might be lawful and it might be a public place, but their actions appear to suggest their motive is far from innocent.. if they're reading this? Come here and provide an explanation!
This is why people are resorting to on-board cameras, whether they're in a car, on a push-bike or lorry etc... driving like this is becoming more common.
Absolute idiot! Went flying past me on the A6 as if I was standing still (I was doing 40mph in the limit), the idiot then slammed on his brakes as there was a speed camera, before forcing his way through the traffic and speeding off again.
A menace on the roads
