I firmly believe that autonomous taxis are 30 years away. The big benefit will be for long haul trucking. That will be here in 10 years or less. They will have special rest areas where the autonomous trucks will park. From there they will only drive on interstates for long distances. When there, they will park at similar special rest areas. Local drivers will then take over and do the more difficult driving. It could really reduce costs as these trucks can drive 24/7 and we can even have them immediately turn around with another load from another company. This could all be completely automated. These rest areas are also a great place to put in charging stations to move these all to electric. By removing most of the narrow streets, cross traffic and unexpected pedestrians, it will be a lot safer.

It's taken more than a decade to get to autonomous trains and autonomous mine trucks (Rio Tinto have sunk a lot of money into it), so I wouldn't hold my breath.
