Most people should be doing most of their charging at home. As someone pointed out downthread, level 1 (120V/15A) charging should be sufficient to cover most people's daily driving needs as long as they can keep the vehicle plugged in while they're not driving it. Obviously this is much easier for some (people who own a home with a garage) than others (people who do not have a garage or other fixed parking spot) but that's a problem we can fix gradually as electric cars gain market share.
