GAME CHANGER. Why? Think of all the people that can be mobile. Blind, disabled, elderly, and on and on. You could use them as a part of a mass transit system. Suppose I get on a high speed rail line to Calgary, arrive, get into a self driving car that drops me off at my meeting, then picks me up at the end, and takes me back to the train station?
Do I want one to replace the Miata? Of course not! But, if they're EVs and used in fleets as part of a larger strategy of moving people, they make so, so much sense. The fact that the car can leave a passenger somewhere and then move to a new location on it's own opens the door to so many possibilities.
