I just gave a talk on flying cars. It turns out technical difficulty is not the reason we don't have flying cars, or self-driving cars.

Innovation is one way new technologies can change the world. For example, the reason we have skyscrapers is due to the elevator brake.

Elevators have existed in some form or another for over 2,000 years. But without the modern innovation of the elevator brake, nobody felt safe being hoisted by a rope up into the air, where a fall could kill you. And nobody looked forward to walking dozens of flights of stairs. A new combination of a spring, gravity, and a ratchet-and-pawl (all existing for over 2,000 years, the same as the elevator itself) gave humans the feeling of safely moving up and down in space that they didn't have before.

But innovation is not a guarantee of success. Electric cars have existed for 190 years. Their innovation, combined with the development of modern batteries, made them the most popular car by the beginning of the 20th century. But two decades later they disappeared, when cheaper, more convenient, more useful gas cars became available. It took another 60 years to develop a new production EV.

In comparison to land-based vehicles, drones are used to fly automated GPS-coordinated routes around the world every day. There are about 31.7 Million airplane flights over the USA every year. And even though 37,000 people die in car crashes every year, only 399 people died in air crashes in 2017 (world wide!). Not only are flying vehicles clearly safer than driving, we can very reliably coordinate flying vehicles.

So why don't we have automated flying cars? Nobody decided to build them. Until startups like this one do the actual hard, long-term, complicated work to coordinate all the necessary pieces, and can figure out how to make it both convenient and cost-effective, it just doesn't happen. And the same is true of self-driving cars.

Until someone decides to coordinate all the complicated parts to get it working, it doesn't exist. Sometimes this takes convincing society to make compromises - like, you don't get the "freedom" of piloting your own vehicle, unless you are very very well trained to do so. And sometimes it just takes lots of elbow grease. Personally, I think we need more of the former than the latter. But I'm glad this company is taking on both challenges.




What unless ? This is fun. I understand most of the engineering is in regression, but still making things that fly is fun. Only problem is money.
