Well, it doesn't sound appealing to me either, but unfortunately appeal has
nothing to do with it when it comes to millions (!) of people flittering
hither and thither in their own personal craft in a major metropolitan area.

This is currently how we do it with cars. No autopilot.

Getting people safely from point A to point B has.

Cars aren't terribly safe, but are very popular.

Actually, I think personal appeal has the biggest part of the success
formula for "plans" like this. If people just plain don't like it,
they won't use it.

I think that's why mass transit is such a failure almost everywhere,
even though it's safer and hugely more efficient - arguably, "better".
People just like having the little bit of control they get driving
their cars. Sometimes it's the only control they get on any given
day.

Telling people, "It'll be great, just push the button, and sit back
and relax" generally is a recipe for failure.
