Earlier quoted context omitted.
You are factually wrong. The general case is being solved. Self-driving systems are objectively better every year, and will eventually reach human level safety. You can literally watch cars self-driving in all kinds of places and conditions. Yes, they make mistakes. So do humans.
So when will these self-driving cars be ready for mass consumption? Because they're starting to sound like flying cars at this point. Yes, technically doable and there are always some working prototypes, but no real market, and not seen as practical.
- at current traffic levels, accidents are rare
- but fatality rates are high (20% of helicopter accidents)
- the commercial carriers have much better accident statistics than general aviation
- commuter and on-demand flights are much worse than commercial scheduled flights
- rather more than half of all accidents have a root incident near an airport - taxi-ing, departure, initial climb, approach, landing.
My conclusion is that mass adoption of flying cars (as in, millions of people piloting small aircraft with varying levels of maintenance, safety inspections, training, and traffic control) would be a terrifyingly foreseeable disaster.
On the other hand, I hold out real hope for fully autonomous vehicles being potentially safer than a distracted teenager on the road.
