I think the only difference between car drivers and motorcycle riders is the fact that on a motorcycle you are far more vulnerable to serious injury. There are bad motorcyclists and bad car drivers. Conversely the opposite is true. A good motorcyclist, who sticks to the speed limits and drives carefully is still at the mercy of other road users and their mistakes. We have all made mistakes and errors of judgement, probably more so when we were younger.
The clip of that crash brought more questions to my mind. Yes he was speeding but did he have his headlights on? All immaterial now as the poor lad is dead.
It is not good to generalise but certain car makes and models, in my own experience, seem to have more aggressive / faster drivers. BMW / Audi. / Mitsubishi Evo / Impreza. Most bikers enjoy a bit of speed, as do owners of certain cars, so it is not surprising that our own experience on the road seems to confirm the stereotype. There will always be exceptions to the rule.
A neighbour, a young chap in his mid 20's I guess, has pranged his cars nearly half a dozen times to my recollection. He drives fast and aggressive but obvious hikes in insurance do not seem to slow him down. He now has a motorbike! Watch this space!
