Yeah, it works both ways as well. Seat belts save more lives than they take. They do kill.
I watched a girl die in a Corvette because the seat belt held her in place when the car got t-boned by an old lady in a LTD. The driver of the Vette got squeezed out like big zit and lived, she didn't.
That was an exception I suppose.
My brothers face got bashed in and he almost died because he wasn't wearing a seatbelt and I got my noggin rattled once in a wreck because I didn't have one on.
I will never forget that girl in the Vette though. That was the most horrible thing I've ever seen. That memory makes it really hard for me to put it on, but I do anyway.
