You'll have to excuse the weirdness of my analogy, but I'm tired this afternoon :
It's like we all have one car. There is a problem with the transmission (smoke from Mexico). There is a problem with the brakes (pollution/smog created locally, like in Houston). We take it to the mechanic (The state or city or county depending on problem). They decide to work on changing the tires (ban smoking in restaraunts) and they repaint the car (lower the speed limit).
In other words, they are slapping a fresh coat of paint and new tires on the car and saying it is fixed, when it didn't address the car being able to move or slow down (Mexican smoke or like the smog/haze that is around Houston) or addressed something that wasn't a problem (smoking in restaraunts).
One of the worst analogies ever I know :-)
