The gas mileage seems off. I have a small SUV (Mazda CX3), and since there was no category for that (maybe the small SUV market is too USA-centric), I picked a "Medium car" (lke a VW Golf).

But it gave the gas mileage as 18 mpg, while I get a measured 30 - 32mpg on my commute. Even when I had a golf, I was getting around 25 mpg.
