Every year cars get a little better, but we’re in for a period of about 5 years in electric cars where each year’s new model is a lot better, and that’s trouble for people trying to sell them. To top it off, in a few years robocar features will start getting more serious (starting with the first no-supervision traffic jam assist), and so other parts of the car will also be on the Moore’s Law curve. How might a taxi model for robocars mitigate this?
