The 'Uber Driver' may not be at fault, however the car failed to prevent or avoid an accident. It suddenly appears self-driving cars are no safer than human driven cars. Of course these are purely speculations but valid points.
Interesting to see it's flipped itself somehow, too, I wonder what the computer decided to do that it maybe shouldn't have done? I suspect Uber will keep very quiet on this one, as there's all kinds of assumptions to be made.
