That would likely look terrible. I think the idea is to create a "Normal" looking car that that performs decent, with the bonus of not "requiring" gas for short trips.

I completely agree. Fender skirts would look awful. However, if enough people express interest, the aftermarket will supply you. I have a feeling that any real efficiency gained would most likely be in your head. Kind of like the tuners that put a big obnoxious muffler on their Civic believe they just gained 20hp.
