You have a charging station built into walls of your house already. In fact, there just might be electrical receptacles all over the USA!
So disregarding the fact that they require special connections let's review why you want me to use electric cars...
1. Emissions. This is a fallacy since you are transferring the emissions to the power station. There will be very little savings if you consider this.
2. Expense. This is offset by the cost of electricity. Want to see the electric bill skyrocket? Plug in your car every trip to the store and watch it rise. Speaking of that, charging stations outside of the house will also charge for the electricity used based on their billing which will also include a bit of profit making it cheaper to charge at home.
3. Maintenance. I don't see any savings here since the batteries in the electric cars are very expensive and can't be changed by the user. Most of the electric cars also have very complex circuitry making them very mechanic exclusive.
