Notice that the article cited mentions Uber as one of the players in the autonomous vehicle arena. I believe that taxi cabs will be the first vehicles to use this technology in a big way. Riders now use their cell phones to summon a cab. Summoning a driverless cab will be done the same way.
After the early adopters take their first cab rides and live to tell about it, and the news reports are broadcast, trust in the technology will grow and the political and social barriers will be that much easier to overcome.
Cargo planes will be another area in which this technology is used. As FedEx chief Fred Smith says, the planes can fly themselves right now. It only remains for the use of the technology to be approved. The first self-flying planes will likely have a pilot in them so society can feel comfortable but that will pass. The next step will be unmanned planes. Then will come planes that are redesigned to maximize cargo space by totally eliminating the space and systems required to put humans in the cargo planes.
