I like it... and I like the idea of a lightweight car like this (as long as motorcycles are legal/valid, so should four wheeled spartan vehicles be) - heck I'd be happy to have such a beast with a conventional drivetrain or better yet an external combustion one.

The wheel covers with vents facing "aft" - i dunno they seem to make sense to me. at the bottom of the wheel (as they rotate) they are stationary to the ground no matter what speed you're going because your tread is also stationary to the ground at any given time (no nitpicking about being on ice or doing a burnout) - but as they come around to the top of the tire they're going 2x vehicle speed forward, and presumably forcing air out. That's air being "pumped" out from under the vehicle, which I think we all agree is a good thing right? And by keeping an active flow of air there will presumably aid in preventing the buildup of heat, as well as of brake dust and road gunk on the brakes.
