You'd be surprised. Motorcyclists make up a substantial fraction of all organ donors in the USA. Fatal crashes for motorcyclists are usually the result of traumatic brain injury while leaving the rest of the body intact -- the ideal scenario for organ donation. Fatal crashes for car drivers and passengers usually invokes significant damage to the whole body.

Sure, but motorcyclist injuries where the rider isn't wearing a helmet are like car injuries where the passengers aren't wearing seatbelts. That being said I was astounded when I was in the Southern US the number of people I saw riding their motorbikes without helmets. Must feel amazing but I would never ever risk that in a million years. You don't even need to fall far or fast for a head blow to scramble you.

It's not just direct impact, rapid deceleration can also be traumatic to the brain and other organs.

Cars have materials designed to deform in predictable ways to absorb shock and smooth the deceleration process in case of an impact.

Motorcycles have absolutely nothing of this sort. Body airbags can help a lot, but are still far from the safety that a car offers.

Personal opinion: motorcycles, as a means of urban transportation not sports or leisure, are for people who don't have an option and don't value their lives highly enough.
