Personal transport first; an obvious advance starting right now (or maybe a year or two ago) is AI for cars - which gets rid of many problems with cars as a byproduct.
Cars are about to be as obsolete as the buggy-whip. There'll be little need to travel when you can just log into a drone at your destination instead. You'll soon be able to convincingly 'be' in any place on Earth from your bedroom.
And cities are going away, because there'll no longer be a need for them when local manufacturing has eliminated most of the need for trade, and VR eliminated the need for groups of people to physically be in the same place to do things together.
And because alienated city kids will be able to download weapons of mass destruction in their bedrooms.
'What did you do today, son?'
'I downloaded the Ebola virus and DNA-printed a vat full.'
'That's nice. Did you clean your bedroom?'
'Yes, dad.'
For long-distance public transport, at least over medium range, maglev is up-and-coming.
But the Internet is faster. About the only reason to need to move your body around in the future will be to go to a spaceport to leave the planet, and a few hypersonic jets can handle that market.
The real point is that technologies always display an S-curve of innovation. What happens at the top of the S-curve is that something completely different replaces a technology when its potential for innovation runs out.
Bingo. Taking current technology and pushing it far into the future rarely works. It's like a writer in 1800 predicting that we'll be riding in carts behind horses specially bred to pull them at 100mph.
Sadly, I don't know anyone writing these kind of stories, so I'll have to do it myself.
