Here’s a fantastic Disneyland video from 1958, “Magic Highway USA” that explains all the wonderful technology we should be seeing today. This includes, color-coded lanes (apparently, yellow leads to Dallas), Ceramic keels that creates bridges as it traverses the crossing, and escalators for cars for crossing difficult or steep mountains.
Unfortunately, it seems that we’ve only slightly improved our roads over those that the Roman’s built. Our usage has increased so quickly that we are in a never-ending loop of repairs and relaying pavement.
I wonder what will happen with the crisscross pattern of highways when we all switch to transporters or flying cars… perhaps we’ll finally have plenty of green space like Boston’s Big Dig central artery re-purposing.
I wonder what the no hover-car parking signs will look like…
