Having my children die because someone's poorly maintained octocopter broke down and flew into the side of my home isn't "natural selection against stupidity".

It's like you think the only victims of drunk drivers are the drunks themselves.

"Worse" was not for people in the vehicle but the people below. After car forced us to be aware of our surrounding when walking, flying car would force us to be aware of the sky too.

How can they be aware of something so high up it appears smaller than the average pigeon?

Alas, that doesn't really work, if catastrophic failure also harms innocent bystanders.

I, too, imagine a person in my head, and then immediately wish that they die in a terrible accident, possibly taking innocent lives in the process, because I decided I don't like the imaginary person I just created. In my head.
