Right now we have fully autonomous vehicles operating within a roughly 100 square mile geo-fenced area of Chandler Arizona. They are overseen by remote operates who intervene when the vehicles get hung up. The vehicles stop and start at predetermined pick up points. But within those constraints, they work. Waymo has been developing the technology for 9 years, and have accumulated nearly 8 million real world test miles in that time.For the last 18 months (or so) they have focused their testing in the Chandler area, but are not yet ready for a commercial launch. For every new area they head into they need to solve specific problems at specific intersections. The vehicles are not yet validated for a full range of weather conditions. There is a huge amount of preliminary work that goes into preparing an area for commercial operations. Developing an autonomous vehicle that can go anywhere as well as a human might just be 10 orders of magnitude than for commercial aviation, but what Waymo has is enough to disrupt.
