While gas is relatively cheap, I still use 15% of my paycheck for gas. That's quite a lot. Granted, I don't make much, but $150-200 a month is a lotta dough.
You also have to realize that people in Europe don't have to drive NEARLY as far as we do here in the U.S. Smaller engines, diesel being 20% less expensive than gas, and etc., $70 to fill up a Mondy isn't that ridiculous.
If gas hits $5 a gallon here, color me broke. OF course, I doubt it will ever happen because of the serious economic impact it would have.
