Reply to comment by syntaxvorlon in Flying cars can actually eventually become a thing by Jalen_1227

Trains are not even 2-dimensional travel, its one dimensional.

That means it's going backwards. Progress is about increasing, not decreasing, our options.

Most trips you take in a car are from one location to a second location and then back. Home to work, work to home. Home to store, store to home. You'll have to go backwards in your flying car too.

Adding another dimension to travel doesn't make it better, and when progress fails to make something better, then that is not good progress. If you want an example of this, check out the notion of 'Induced Demand.' If you widen the roads, the traffic gets worse. Widen them more, even worse. What if the road was as wide as the sky? Then the traffic would block out the sun.

What PT advocates do not seem to get is that everyone works and lives in different places.

There are plenty of environmentalists who think technology which enables more people to live is bad progress, so I don't think I will leave it up to you to decide what good or bad progress is.
