This article @ Green Car Reports and reported elsewhere is an interesting model for charging station locations. Many in the electric vehicle world have envisioned some day the majority of parking spots having some form of charging available, but it’s hard to justify right now. It might work ok for NYC if done properly as we imagine lots of folks drive and park in the city, but they are still many variables that eventually the market will figure out. These include costs to charge if any, reservation of the parking spot with a charging station vs random parking as is done now and so on. Eventually it’ll happen because already certain charging areas like Los Angeles Airport and other locales are already overwhelmed with EV’s.
