An auto-pilot is fine for aviators. Often you can glide for a while in an emergency. It's not 100% risk-free of course, but planes are assumed to fly in empty air and pilots are trained for various emergency scenarios. I don't even think autopilots in planes are linked to radar, so in all likelihood they are just assuming empty air.

Not so vehicles. Technology is completely different. Why are you comparing apples and eggs? In a scene, there is a lot to interpret. You interpret wrong once per million hours, there will still be a lot of casualties. And that is just road pattern recognition. By plowiing into policemen by the roadside (in China, reported by ZH), Tesla's autopilot has shown an inability to intepret anything higher-level.

So, really why are you comparing apples and eggs? Why are you even making such an argument? Maybe because you have Tesla stock? I have actually read plenty of the DARPA Grand Challenge research papers, I have no doubt rollout of the tech will get lots of people killed. Nobody has a magic solution. It only sort of works in controlled conditions, for example, limited low-intensity routes.

Unleash Tesla autopilot on the general populace? Manslaughter 100%.
