Why anyone would do proper seatbelting "preventatively" when you have airbags and your car is built with crumple zones and just a low level general risk of getting in what is mostly a fender bender is honestly crazy to me. We now understand how collisions work, where they happen, how to build cars safer (ie with more airbags). There's no reason to remain so scared anymore.

Edit for context: I don't literally think this, I was mocking something from the removed comment
