I'm kind of curious why someone hasn't made an electric commuter car. A one seat, three wheel vehicle made exclusively to go to work and come home. You can probably make it very lightweight and relatively inexpensive. If it looked cool and had about 100-150 miles per charge, maybe throw a solar panel on the roof to charge in the lot... I'd definitely buy one. Heck, I drive a two seater to work now because I can't see hauling an SUV with me when I go to work by myself.
First half of your description fits a Smartcar to the T.
