We're all susceptible to being deluded by our naive realism. Like how I think anyone driving faster than me is a maniac and anyone driving slower is a moron. The objective reality is that everybody thinks that.
If the motorcycle were invented today, do you think it would ever be legal? In America, perhaps, but probably not in countries that are more heavy-handed with regulation and bear the costs of public healthcare. It's an insane and dangerous vehicle.
I have several friends who have survived nasty car crashes and fully recovered. The only one who had a nasty motorcycle accident... well, his heart's still beating, but I'd hardly call it life.

Findings from motorcycle safety study.
75% of accidents were found to involve a motorcycle and a passenger vehicle.
Almost half of the fatal accidents show alcohol involvement.
In the multiple vehicle accidents, the driver of the other vehicle violated the motorcycle right-of-way and caused the accident in two-thirds of those accidents.
The report's additional findings show that the wearing of appropriate gear, specifically, helmets and durable garment, mitigates crash injuries substantially
The failure of motorists to detect and recognize motorcycles in traffic is the predominating cause of motorcycle accidents.
Wow, that's even worse than I expected, relative to a baseline that isn't very safe to begin with. It's unconscionable to keep these on the road.
(And others, often involving pedestrians.)
I'd expect most of the accidents caused by motorcyclists to involve excessive speed.
From a completely callous perspective, we'd miss all the healthy young organs that enter the donor pool. They don't call them "donorcycles" for nothing.
