Gasoline Guilt Week: Day 2

So if you go on the LA MTA website and plan your bus route for your trip, you'll notice at the bottom:

I had to wonder, how logical is the 56.2(!) cents per mile average from the AAA, especially when one drives a hybrid? I used this link to figure out that it supposedly only costs me 20 cents per mile. But then again I didn't factor in the $370 I just spent on tires today, so maybe that adds a penny or two. But it is pretty impressive that there's a AAA link on a public transportation site, as they are notoriously pro-car. Hmmm. I'm not sure I'm ready to give up the 'brid even if it saved me $12 a 20 mile trip.
