Maybe motorcyclists where you live place more value on the lives of others (and, presumably, themselves). I don't think I have ever seen a motorcyclists who wasn't driving recklessly, whether by speeding, driving between lanes of traffic and then forcing their way in, undertaking, overtaking on bends, or driving way too close to the vehicles in front, presumably to attempt to intimidate them in to pulling over. They seem to be aggressive, impatient and without regard for their own safety, let alone that of other drivers. And I certainly would not say that this is a minority, certainly not where I live anyway. I also have personal experience of how dangerous these idiots can be - my parents were almost killed by a motorcyclists who was driving towards them on the wrong side of the road, overtaking on a blind corner. The car was a write-off, and the assessors said that had the wheel struck one inch either side of where it did, it most likely would have driven up the bonnet and through the windscreen.
