I don't consider myself an "old timer" (I'm 32), but as a student of auto history, I know a little more about the seat belt part of the trivia.
Nash was the first U.S. automaker to introduce seat belts as an option in 1949. They weren't advertised as a safety feature; instead, they were meant to hold a sleeping passenger in place while driving!
Ford and Studebaker joined in with optional front seat belts in 1956, but people didn't take to them. And it wasn't like they were all that safe anyway ... the outer halves of the belts were attached to the doors! Door pops open in an accident -- instant ejection.
Studebaker was the first, however, to make front belts standard -- lap belts, not at all dissimilar to what I've got in my rig -- on their cars built after February 1, 1963. Buyers could delete them, however, for a $15 credit.
