Electric cars can be better than fossil fuel cars. Driverless cars are probably safer than ones driven by humans. Shared cars reduce the number of cars necessary. Taxis reduce the number of cars and the amount of parking necessary. Put it all together and a lot of people can get transportation more cheaply, while reducing the transportation infrastructure, while reducing pollution. It may be inevitable because the economics are so powerful, but it will take a while. Now, however, is the time to prepare for it.
