Re: So what's the story??
The story is that a large chunk of metal on 4 wheels, probably moving very fast, and quite possibly under the active control of an AI system (the other big selling point of this car aside from being electric powered), has killed a road user. Non-AI cars killing people is not big news as this is sadly common.
The growth in the number of AI controlled cars is a big deal for all sorts of reasons.
Most people in charge of cars and bikes are on occasion incredibly careless and slipshod in the way they control their vehicle of choice - this is why lots die and are mutilated every year on the roads. AI may be a way of reducing the carnage (pardon the pun).
There are well understood and established laws and principles which determine how the people involved in vehicle related incidents are treated by the legal systems.
It's still early days for how AI systems will in practice affect this whole area of the law.
Every day, large numbers of people get away with their random stupid driving or cycling choices, but when something bad happens as a result and someone is hurt, the legal system will often examine the what the people involved were doing and their reasons for acting as they did.
AI control adds a whole new level of complexity to this exercise, such what was the AI doing, how was it designed to manage the situation it encountered, what AI settings/options did the "driver" select, did the AI actually do what it "should" have done, etc. etc.
