Congratulations that you haven't, that's evidently because youre not in there correcting people when they claim that autonomous cars aren't a solution.

As long as cars are on the roads and humans are driving them they will continue to kill and maim people. Autonomous cars are the only remotely viable solution to that. They might not be fully ready for all situations yet, but they will be ready on the scale of a decade or two, whereas reorienting north American society to minimize human drivers (get everyone to move out of their homes in the suburbs and country) will take literally generations.
