People generally know how to fall and not hit their head, and when they do their body softens the impact. Not such much with scooters and bikes, where you can literally go head first.

There are risk factors, then there is absurd. Racing drivers drive a lot faster than road vehicles, they also have minimal creature comfort protection like airbags because the car has to be light. They have roll cages however that you can thump your head on.

I suppose we could all walk around with goggles because y'know, someone might poke their eye put.
