Or we could have trains, subways, bicycle lanes, roads for cars and delivery trucks which we drive ourselves, airplanes and ships. Why do we have to reinvent the system we currently have? It works. Trains for long distances, trucks for the last part. Cycling in cities (at least in NL) and cars for longer distances. Subways, trams and busses for public transportation in larger cities, trains for travel between cities, ships for massive cargo, planes for fast casgo and traveling really far. More and more is changing to electric. We shouldn't replace all roads with train tracks for individuals to use just because they are too lazy to drive themselves. There's lots of work to do in the US, as that country is made for cars only. Look at The Netherlands, we've done a really good job changing everything to cycling and public transportation mainly. Or Denmark. Kopenhagen is insanely well designed for bicycles and public transportation, even though it's a really old city. Tokyo is huge, their public transportation system is insane, it's perfect in every way.

If you're going to complain about train tracks in rural areas being in disrepair, why not repair them? Here in NL we have a track replacement train which drives at night and replaces the entire track during the time the track isn't used. No manual labor, fully automatic.

Just because the US doesn't repair and upgrade the systems they have and stubbornly sticks to mainly road travel even though there are many countries which have shown that doesn't work but changing does, doesn't mean we have to invent new stupid shit because the American infrastructure is so extremely dumb.

We will always need some cars/trucks/semi's, we can just switch most of it to other forms of transportation which are already out there. Just learn to drive if you really need a car, it's not rocket science. Otherwise take the buss.
