One can fill up a gas powered car with enough fuel to last a week in about 5 minutes or less. The area required to keep a city full of battery powered car depends on the amount of time it takes to charge the battery. It takes a considerable longer amount of time to charge a cars battery than it does to fill a tank with gasoline. There is not enough space in the city I live in to provide charging stations for all of us who want to own cars. Plus no one is talking about the added strain on the electrical grid.
