Why Didn't We Think of That???

In a speech on Wednesday, 7/30/08 Obama stated the following: ...all we have to do is "properly inflate our tires and tune-up our cars regularly" and it will do more for our oil dependence than allowing more off shore drilling. Gee--why didn't we think of that before? What would this world DO without Obama? Of all the years we've been dependent on automobiles, why haven't we thought of maintenance? It's too bad none of us can afford the oil when we take our cars in to be "tuned up." Jack ass.
