1976?
GM's Motorama exhibit in 1956 featured a film that looked into the far distant future of 1976 with predicted a jet age future with electronic digital displays and an On Star like central command that would guide us along our uncrowded path to adventures.
I remember as a little kid, my folks lived in Wash DC region, I born there in '44, and so being the family was from Cleveland Ohio, they'd make the trip maybe twice a year, so I"d ride in the back seat of course for the long trips, taking about ten hours, then this miracle highway opened up, the Pennsylvania Turnpike, predecessor to the interstate highway system.....it was built with private funds, BUT it took the route of some RAILROAD tracks that had even been blasted through some mountains forming tunnels that were rather impressive....the highway ran from east Pa. all the way to the Ohio border, where the roads became shitty and slow again.....we drove mainly Maryland roads to a town called Breezewood Pa. there to head west to Ohio....eventually the other roads improved, and the travel time was cut to 6 hours or so, The Pa. Turnpike was the first interstate highway...it was a toll road of course, being private property....:shocking::beer:
