Visualizing Gas Mileage

Bankrate.com has a nice tool for estimating how far a car will go on a tank of gas. The visualization of the car's movement thus strays from the more-frequently emphasized metric of gas mileage but the charts do highlight the "cost per mile" using gas prices provided by the user. I'd like to be able to compare cars across classes rather than just within them, though.

Only bug is that the price per mile drops the tenths if cents are in 10's - $0.10 becomes $0.1, etc. Whoops! [Via|Link]
