Reinvestment or Recovery?

I was in my car heading up the road to visit a neighbor this morning. And advertisem came on the radio suggesting the wisdom in keeping your gas tank above half full in case of emergency. Good advice I suppose if not obvious to most people. The gist was if the power went out or if there was some kind of emergency it would be advantageous to have gasoline in the car so one could move about if necessary. What really caught my attention was the ad was sponsored by the American Reinvestment and Recovery Act. I wondered if this was really something that needed to be invested in by the government and was it a worthy use of tax payers dollars? Someone obviously thought so, but it seemed to me an odd thing to be covered by that act which was supposed to do much more than buy radio ads and appears to have not happened the way it was designed, no matter the good intentions.
