Helmets are also insufficient on bikes but they significantly reduce injuries. With cars I'm not quite sure what problem you would be trying to solve because they probably wouldn't actually appreciably reduce injuries (I don't many of those car deaths are just really simple trauma to the top of the head that a helmet would actually protect against)

Oh come now, top of the head? Full face helmets are the better option, and if we're really looking to be safe, we should require them, and anti-whiplash headrest connections, as well.

Similarly six-point restraints, I'm always confused why there's just a lap-and-shoulder belt in most cars.
