This just might work. Walmart may sell an inexpensive electric car. The company already has a car parts department and a car repair department with garages and lifts, so taking on service and maintenance of one or two cheap electric cars would not be a stretch. I think that over the next five or six years, as older second cars in families wear out, many will opt for a cheap electric for around town errands. Electrics may be good for families with teen drivers--the slower, low performance vehicles will get them back and forth to after school jobs and friend's homes, but the cars won't be taking curves on back roads at ninety.
