I assume by "mileage" you mean "range"? But yes, the Leaf has a shorter range than the Tesla Roadster, and is also a lot cheaper. Price vs range is the basic tradeoff when building an electric car. Nissan could build a more expensive Leaf with a longer range if they thought there was a market for it. I like the Chevy Volt's best-of-both-worlds solution, since it will do your sub-40-mile commute on electricity but still fire up its petrol-powered generator if you want to do hundreds of miles on the weekend. For an electric car, a zero risk of getting stranded is a huge selling point.
