TV commercial for a new 50 MPG car?

So, I am watching the History Channel and a TV commercial comes on with a car driving down a country road. The voice over says "what can a car that gets 50 miles per gallon do for the environment?" It's not a Honda or a Toyota, so my interest is piqued. What can it do? "Not as much as the car that carries it" explains the voiceover as the car drives into the back of a train, somehow in the middle of a road. The voice over then says CSX trains can carry a ton of freight 426 miles on one gallon of fuel. Thanks for getting my hopes up, CSX. You can watch the dissapointing ad at CSX's website.
