If you’re a normal, physically-able person, you can (you know) WALK to the train station. Or ride a bike. Most stations are spaced a mile or two apart, which works fine for anyone who’s not a complete gimp. Door-to-door transportation is actually a bad thing which will discourage human activity.
I’m for slow technological progress — a perfect utopian world would actually be very unhealthy. The utopian ideal will just isolate people from serendipity and public life more, as if Americans aren’t isolated enough.
Individual transportation already uses a lot of energy and fossil fool. If we make it cheaper/faster/more convenient combined with low oil prices, it will translate to EVEN more fossil fool use.
Not good for the climate unless you’re one of the brainwashed cretins who denies that it’s a problem.
