I’m also sixty-seven and when we went on vacation my brother and I stuck our bare feet in the back windshield, and wrestled in the back seat. My parents seemed to think we were fine without car seats. It was also a lot of fun.
On long trips I have been known to sleep on the package shelf in the rear window. My sister who was older got the seat. On at least a few occasions a quick stop sent me rolling off on top of her. I can remember sitting on my dad’s lap and steering wheel while he worked the peddles. I guess I was his airbag of sorts.
