When my sister and I were kids, we weren't restrained in the cars at all, lol. Dad always tucked the rear seat belts under the back seat, which was a common practice back then.
Then when I turned 16 my first daily driver was a 56 nomad that didn't even have seat belts. LOL Drove that car up into my early 20's before I parked it.
To some of you it's probably a miracle I'm still here
