The idea that Earth being accessible to everyone at infinitely faster speeds is not a dark age. That is a golden age. It's sad that you've confused the two, but it's modern propaganda at work. The environment is damaged by humans. Not cars. If we banned cars, people would still ruin the environment, just in different ways. But that's cutting the nose off to spite the face.
The truth is, cars are, for the most part, amazing pieces of technology that allows nearly every person freedom of movement. You aren't going to change that without creating something better.
It seems like electric, self-driving cars are a possible dream, albeit even close to a pipe dream. Cars none-the-less though.
The reason StreetRoadTopia is a dark age is not because there are streets and roads per se, it's that the Pedestrians, in their hubris, smugly abolished Stroadlandia. Whether we get there by streets, roads or stroads, the real golden age is the friends we made along the way.
Car only allows you freedom of movement because the infrastructure are developed for cars. You would be singing a different tune of freedom if it were trains and bikes instead.
Stroadlandia is like meth or heroin? I didn't realize I was experimenting with something tantamount to drugs. I suppose it was a good trip, but one has to keep on dunetreading.
Stroadlandia is a noble, and beautiful place. Her cars are majestic creatures, worthy of human service. Her department stores and parking lots overflow with the abundance of a multifaceted thoroughfare that defies the reason of mortal man.
I will never forget what I learned from my time living with the Stroadlandians as a pedestrian. I shall wear your downvotes as badges to their honour. Long live Stroadlandia and her humble denizens.
