Solar roadways are a crappy idea because asphalt and solar panels have completely different engineering requirements, and roads don't even have buildin electrical lines. No contact, no moving part, already electrified and pylonified maglev on the other hand...
What you say is true, but also a condition that is spectacularly unlikely to change.
Separately, for personal travel, I will sometimes travel low-and-slow, but there are many personal trips where I want to go somewhere for a long-weekend and getting half-way there and turning around doesn't accomplish the goal of the weekend. Even for a week-long vacation, I don't want to spend 4 days getting there and back.
Unfortunately, you're probably right.
Still I don't believe high-speed maglev will solve anything. Less planes, for sure but more people traveling further, more frequently, more efficiently consuming more power in absolutes.

I understand, and feel the same. But I do my best to find a closer destination that's "also" nice, and make sure that when I travel far only when I have proportional amount of time to spend there.
When you're trying to escape New England winter weather and get to someplace warm with 11+ hour days (or escape the heat and humidity of Florida in August or visit family), that can be inherently difficult.
Makes you wonder how people in New England winter or Florida summer used to cope a century ago. :-)
I would be in favor of banning flights between city pairs that already have an equivalently high-quality rail link between them, though.
But making trains faster and faster will not improve things as they'll also compete with other forms of transportation (cars, slower trains). If the faster train now gets you 800km in 3 hours, people will travel 800k where previously they spent that time traveling only 500km. It's Parkinson's law.
Personally, I hate traffic jams, cancelled trains, flight delays. But I love spending time hiking, cycling, or driving through the empty country at my own pace. More so if I get to spend time with friends and family, for sure.
Because fast travel is... fast?
> What is it exactly that we hate so much about traveling?
Most of slow travel is extremely boring.

I enjoy those things, too, but I don't want to spend a week traveling somewhere when we have the means to travel there in under a day, for example.
Edit: besides, cheap fast travel allows you to spread people to more places, and not require them to bunch up in a few overpopulated cities.
The strength of cities lies in their density. A well planned city has short commutes. Long distance transport ought to be mostly for goods, not people. If people travel far, travel slow and enjoy the journey. Relying on fast long distance (business) travel is a sign of organizational immaturity at some level.
