They were invented decades ago.

They have fewer moving parts than wheelbois.

They require less maintenance.

There's obviously some bottleneck in expanding maglev technology, but what is it?

It's basically evolution. It's not that we don't get the best things, it's that when something evolves traits that require more energy than they are worth, they inevitably die out. I'm reminded of the film The Man in the White Suit.

It'd be nice to always have the "best" things, but the "energy" to support them has to come from somewhere.
