Absolutely nobody made an argument that they don't want to use seatbelts because then they'll just start crashing all the time.

(I'm old enough that seatbelts weren't a thing when I was a kid, so I remember well the arguments when they became common and later required.)

Tons of people thought seatbelts would do more harm than good.

After reading the Superfreaconomics chapter on child seats I can believe seat belts do quite some harm in accidents.
