From what I read, the victim was jaywalking, and in AZ
jaywalkers are supposed to yield the right of way to traffic.
Also, the UBER car was doing 5 under the speed limit.
Those factors will probably shield UBER from any criminal charges.
Having said all that, I don't like this idea of "driverless" cars.
It's one thing to have a robot cook your hamburger,
but removing spiritual elements such as compassion
and sympathy out of dangerous activities is not wise.
