Yup. Dead people are certainly a public safety concern. Pesky dead people!
So did he try to activate it or not? If he attempted to activate it but did not complete the sequence of events the car should have been overt about warning about it. Perhaps before you can use it they should require people get trained on how to use it correctly?
The public should not be beta testing software of this type on public roads. There are many other methods to do so with better control, specifically trained employees in direct or indirect employment. It could be tested on fleet vehicles or the like.
Its still only driving in ideal weather and road conditions, while a nice feature its just an advanced cruise control. It certainly does not earn its name "autopilot".
Lets be honest, any other company doing this would have been accused of recklessness
On another note, it's interesting how often the autopilot is often blamed despite not being on. Thankfully that can easily be verified. The damage has been done nonetheless..
