The "Water Fueled Car"

[roguebanshee]

Then you are ignorant. Consumer reports has a list of the most efficient cars that they've tested. These are the only ones getting over 30 mpg:

And I thought the overall bad mpg of the US was just a myth. I am reminded of the hostage scene in Robocop with the mayor.

Lt Hedgecock: What kind of car do you want?
Miller: Something with reclining leather seats, that goes really fast, and gets really #$%&ty gas mileage!

Most new cars around here (Denmark) get 15-20 km/l (or ~38-50 mpg) with mixed highway/city use and a competent driver. One VW model got as much as 30 km/l (or ~70-75 mpg) but it's not in production anymore, apparently due to bad worldwide sales. Bigger cars do get a worse fuel economy, but those are also a lot more expensive to both buy and own (taxation of cars is partially based on fuel economy). I'd toss a link, but the only site I know of with impartial tests requires paid membership and is in danish.
