Fully autonomous self driving (level 5) is still a bit off but the existing technology is very impressive. Waymo has self driving cars in Phoenix (level 4 but geo-fenced, I believe). Teslas are very impressive and don't rely on geo-fencing (in other words, it will work anywhere). If you haven't had a chance to drive a Tesla with autopilot then a trip to Orlando would be an eye opener. They are fully capable of driving themselves on highways - steering, braking, accelerating, lane changes, off-ramps - you must keep your hands on the wheels, a light touch is all that is needed. Teslas can now recognize stop signs and stop lights (some of the time) so non-highway self driving is now starting to become a reality also - you will still need to keep your hands on the wheel and will need to assume control in some circumstances. Since their software is based on a neural net, it continually learns based on the data collected from most of the Teslas on the road. The amount of hardware on a Tesla, the compute power to run the neural net and the array of sensors (cameras, ultrasonics, and radar), is impressive. The regulatory issues are probably more of a challenge than the technology issues. The technology issue is software as Teslas contain all the necessary hardware for full self driving. I would not be surprised to see Tesla at level 3, or possibly level 4, self driving in a couple of years and fully autonomous level 5 self driving within 10 years. Tesla is currently at somewhere between level 2 and 3.
