I checked it out and it's pretty interesting. You input the miles you drive annually and what kind of car you drive (gas, diesel or hybrid) and it gives you data on things like how much gas you won't have to buy, how much money you'll save, how many pounds of CO2 you won't create, etc. It's interesting stuff, but it would be better if they let you input the current MPG of the car you drive also because then the figures would be a bit more accurate, still it's interesting.
