You simply open up the app, summon the cab and then it arrives.
Once inside the cab there’s a touchscreen and voice-activated assistant who helps you choose your destination.
Once you’ve decided where you’re going that’s it, you sit back and let the car do the rest.
Now there are some caveats.
For starters the cars are assigned to predetermined routes in much the same way busses are, so as long as your destination is along one of those you’ll be fine.
Secondly this is a very early field test which means the cars are only going to be travelling around Yokohama in Japan where they’ll be driving to and from Nissan’s global headquarters.
