Yet another thing not mentioned in the article is the effect on the energy grid: as we move towards renewables, which are much harder to turn on and off to match demand, we will need to invest a lot more in energy storage. Large scale deployment of electric vehicles might be a way to solve this problem, if one were forced or incentivized to leave their car connected to the grid when parked, the grid could use the cars as a distributed storage system.
