If there are two things that Japan is one of the undisputed masters of, it’s robotics and transportation. That’s why it’s not all that surprising to see that the country will begin testing self-driving taxis outside of Tokyo starting next year. The tests will involve using autonomous cabs to drive about 50 different people a couple of miles from their home to local grocery stores, in the hopes that a commercial driverless transportation service can be developed within the next few years.
