Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Display:
I think trains for the countryside powered by networked solar energy farms and panels next to the tracks. Electric jitneys for the last mile callable by app.
For cities trams are best, we probably have the tech to bury the cabling, (which looked a bit dodgy back in the day.)
Electric single and double seater runabouts rentable by the day with stacked underground parking lots, no more need for private vehicles at all, leaving streets flowing and easily navigable by pedestrians. They could drive themselves back to the recharge base after use.  
All engines governed by speed limit sensors, and all external surfaces coated in multilayer foam rubber to minimise damage if someone walks in front of (or drives into) your car.
While we're at it, let's do international droneports for sky travel, no need for lengthy runways that way.
All buildings should be clad in solar panels to juice all this to-ing and fro-ing.
A lot more of us will be working at home by then, shovelling and crunching Big Data, maybe coding robo-software on UBI, hoping to get lucky and win a new disruptor jackpot prize.
Travel as we knew it may go out of style as virtuality comes to you, the world looks more the same all over, and tourism is now more located around the Van Allen belt.
Ah, better now, back to Brexit.
