Yeah but does riding with your hands in your pockets perceptibly increase the danger to other road users....
Of course.
Firstly, the car behind takes a slightly wider line to overtake him. This slightly wider line puts said cars offside wheels about one foot to the right of where they were, which happens to be in a pothole - a common occurrence on the roads you'll agree. Unfortunately the pothole is full of water, which splashes up violently (car was overtaking quickly due to their concern). The water splashes up into the face of a motorcyclist the other way, making him flinch and giving him a momentary speed wobble.
The speed wobble, as they tend to, flicks the back wheel out. This, plus the power to the wheel cause it to spin and lose traction. Luckily the motorcyclist will recover, but not before his spinning back wheel flicks up a chunk of stone (probably from that pothole) flicking it up and through the open window of a truck driver that has his window open despite the rain as he's not allowed to smoke in his cab.
The stone smacks him on the temple, stunning him, causing a loss of consciousness for a second or two. This is long enough for the truck to veer into the petrol station on the left, knocking out all the pumps. The cab embeds itself in the forecourts shop front, and the cigarette the driver was smoking teeters once or twice between the window shelf and the door before it drops, bouncing off the drivers step into the increasing pool of fuel.
The resulting explosion is felt by the Cockwomble, still with hands in pockets who is unable to balance, falling off said bike and breaking neck.
What, you've never watched Final Destination? These things happen!
