I'd rather 10 innocent people die to freak autopilot incidents than 1,000 innocent people die because people in general are terrible at operating a 2,000-3,500lb death machine. Especially because everyone thinks of themselves as a good driver. It's fairly obvious not everyone is a good driver - and that there are more bad drivers than good.
Maybe I only see things that way because there have been four deaths in my family due to unaware drivers which could have easily been avoided by self-driving vehicles. All of them happened during the daytime, at speeds slower than 40mph, and with direct line of sight. Something sensors would have detected and braked to avoid.

So going from a dangerous situation to another dangerous situation.
From a risk management standpoint, Tesla's design doesn't strike me as sufficient. Warnings without consequences are quickly ignored.
