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.
