This thing is a disaster.  The concept is marvelous, but it’s a little bit to similar to banging a fat chick.  The air car has no gas costs.  A fat chick; you don’t have to buy her any drinks.  The air car looks like it might be fun to drive.  Fat chicks are generally a lot of fun to have sex with.  The air car is blocky, horrendous on the eyes, and will get you laughed at by all your friends.  I won’t make the obvious parrallel to a woman of larger carriage to spare feelings, but you get what I’m driving at here.  Pardon the pun.  It looks like the thing might actually need a little gas here and there, but for the most part yer cruising around on compressed air.  Yahoo finance has the ugly ass details:

The air car can tool along at a top speed of 35 mph for some 60 miles or so on a tank of compressed air, a sufficient distance for 80% of consumers to commute to work and back and complete daily choresOn highways, the CAV can cruise at interstate speeds for nearly 800 miles with a small motor that compresses outside air to keep the tank filled. The motor isn’t finicky about fuel. It will burn gasoline or diesel as well as biodiesel, ethanol or vegetable oil.

They gotta put a lot of financial lipstick on this pig to get me to drive it.  First of all, the fucking car costs 20,000 dollars.  It’s a third of the size of my car, which cost me 20,000 dollars.  That’s not attractive.  Second of all, it sounds like you are still going to have to buy SOMETHING to make this car run.  Be it gasoline or Mug rootbeer, I dont know.  You still are going to have fork over some cash to keep this air car fueled.  The main issue I have is you’re going to have to pull a Death Race to keep this thing on the road.  You’re going to have to attach machine guns and spikes and roll bars to this tinker toy piece of shit to keep from getting run off the road every five seconds.  That being said, I think even Jason Statham would have trouble making this car look manly.
