Missing the point here?
An autonomous vehicle has killed someone in an accident. No doubt, this is a tragedy, but let's put it into context here.
How many other people were killed on the roads by vehicles driven by humans?
As horrible as it might sound, one death does not necessarily mean there's an issue with autonomous cars. I do appreciate that there are millions more "regular" vehicles on the road than there are autonomous vehicles, and thus millions more journeys that don't result in death, but we simply don't know the facts concerning this accident as yet, so it is far too early to draw conclusions about the relative safety of autonomous vehicles.
