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

You could say he murdered it.

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.

Take any tech bro take on transit, and if you try to perfect it, you'll almost always end up with a train.

It must be a rule on the internet:

There's always a relevant xkcd.

... it’s very hard experimenting when you’ve no idea of potency or dosages.

This.

Fun thing I bumped into a few weeks ago: the guy who's credited with inventing LSD tried a bit to see how it worked and how it felt. But he had no idea just how ridiculously potent LSD is. I forgot the exact numbers, but I do recall the ballpark. So he had a Fermi-estimated 100 μg while he only needed like 10 μg for a good time, so not only did he have the first known LSD trip, he had the first known bad trip.

After reading this, for some reason, the phrase "cryogenic hellfire" lives rent-free in my brain.

Half year day, half year night only really holds on the poles I guess. And it goes paired with a long twilight in between.
