Our gas is about $3.35/gal.
I hear you nana, about driving in the mountains.
I have a Saturn VUE, its a small SUV, 4WD since we live in mountains and the roads aren't always plowed very well. Gary has an old Saturn. we get "decent" gas mileage 20-24 mpg. Which for the US, isn't all that bad, but probably pretty pathetic by EU standards.
IM(not so)HO and while on my soapbox, i think that many Americans think the whole "bigger is better" goes for everything, including cars. why else does someone commuting by themselves really need to be driving a Hummer?
In many areas of our country, we also have very limited Public Transportation and in the NYC Metro area, it is very expensive. I think that helps keep gas prices down because often people have no choice but to drive.
We have a couple of people in our town who drive Smart Cars and my kids laugh (they do look silly when you are used to huge cars/trucks on the roads). but I tell them all of the time, when they can fill up their tanks for $20 and drive for a month and it costs me $50/week-- who's laughing then?
