SUV owners get free gas?!?!
they don't get free gas, they just get a tax break that the author of the article compared to years of free gas.
and the tax break was originally created for things like farm vehicles...large-ass trucks and the like, so that farmers (who the US has a long history of supporting with things like this) could replace older vehicles and still stay in business.
When the law was created we didn't have consumer trucks (Hummer, Escalade, etc) that were even close to the size of vehicle specified in the law. The laws mentioned in the article just grandfathered in the old deductions, so it may be a 2003/2004 law, but the provisions have been there for a while in other laws. It's nothing new, unless you're a writer with an agenda.
