Fully driverless cars are here today, for that matter. But if you want want tamperproof driverless cars that perform well under adverse conditions and are thoroughly tested, then you're going to have to wait a lot longer than "months".<p>I think this snippet is pretty telling: "Waymo chose the Phoenix area for its favorable weather, its wide, well-maintained streets, and <i>the relative lack of pedestrians</i>." (Emphasis mine.) Probably wise, but I'm sure they've already carefully calculated the risk/return vs pedestrian fatalities and are coming out ahead.
