What about those giant quadcopter type things they keep wanting to build to fly from building rooftops in cities for some reason?

Within cities?

Look, aircraft are Hella noisy and if stuff goes bad, they'll smash into buildings. Using them for intra-urban transit is not safe. Besides, I don't know if multicopters can autorotate, which only adds to the safety concerns.

So why not bring it slightly closer to the ground. Maybe put the transportation device on a bridge or viaduct. And while you could put some stairs up from the streets, you may even choose to link buildings into them directly. Most tall buildings have lifts, after all.

Next, giving each building its own link into the system would be excessive. You can achieve 90 percent of the utility if you have larger entry hubs for multiple buildings, and expect people to walk the last mile.

Anyway, back to the vehicle, since a vehicle for a handful of people is rather inefficient, why not build the vehicles for many dozens of people? Why not build it to connect multiple vehicles? If you run, like, four of these, every five minutes, most people will be able to walk up any time and just go.

And to make that movement more efficient, let's have our vehicles roll along a specifically designed path, optimised for minimal friction by using hard wheels on a hard surface.

There, I replaced the quadcopters with a train.

Oh I mean you can replace them, but when nothing of the original system remains you're not so much optimizing the idea as throwing it out to use trains instead

If they really want rooftop travel, a gondola system could probably work.

Works assuming the rooftops are roughly in line of sight. That is something I assumed not to be definitively true in the other comment..
