On December 28 of last year, the Chinese firm EHang reached an important milestone. They flew a completely unmanned, autonomous passenger drone on its first commercial flight in Guangzhou. They were able to transport a human passenger without a pilot, using 16 different rotors and fueled entirely by an electric battery. It made for a much quieter vehicle than a typical helicopter and (in principle) a greener one, too.

If you want to be a little more whimsical about it (and not totally inaccurate), you could say that China has opened a flying car service. The EHang EH216-S can’t drive on a road, but it’s meant to be an airborne form of transportation as easy for ordinary people to use as an automobile.

Before you get too excited, here come the caveats. The EH216-S boasts a range of only 22 miles; by contrast, the most popular civilian helicopter model, the Robinson R44, can go up to 341 miles on a tank. The EHang has a top speed of only 81 mph; the Robinson can reach speeds up to 125 mph, even carrying a max weight of 818 pounds in people and baggage. And while the EHang doesn’t need a pilot, it can only carry two passengers compared to three (plus a pilot) in the Robinson. The EHang is certainly quieter and greener, and may prove to be safer (not that the notoriously accident-prone Robinson sets a high bar), but we’re a long way from phasing out ordinary helicopters, let alone seeing cars get replaced with little drone copters.

Still, I’m happy to see the little guy flying around Guangzhou — and while EHang specifically has been the subject of some financial controversy, I’m excited to see rivals like Joby, Wisk Aero, and LIFT’s Hexa also making progress. They serve as a reminder that some of the biggest questions about the future aren’t about what’s technologically feasible or economically feasible, so much as what’s........
