I'm all for moving over to electric vehicles; they're cheaper to maintain and electricity CAN (but not always is) be cleaner than gasoline powered vehicles.

One thing I didn't see addressed is where the additional electric power for charging vehicles will be coming from. Doesn't NYC have trouble running AC in the peak of summer? I'd be curious to see if additional generation sources would need to be build out, or if the distribution network will also need to be vastly updated.
