I'm forced to disagree. Catastrophic failure would be a feature not a bug. "Natural selection against stupidity."

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.

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