I would like to add that the US enjoys some of the cheapest petrol prices in the developed world so quit ya whinging!
Anyway, apart from your current, very fortunate position what makes you think that the new conservative democratic candidate aka. Obama once in power will not sign the equivalent of the Kyoto protocol. Whatever the rest of the world come up either through G8 summits or otherwise, its just going to increase gas prices anyway through something like a carbon tax.
I hate to say it, but it is going to have to get a hell of a lot worse before it gets better. And the only reason the situation will improve long term is a transfer from thinking gas is the only option...
