Commercial Idiocy

What's with some of these commercials? Why are companies actively advertising to/for morons? For example, the VW ad where the salesman tells the test-driver to "accellerate through this turn". The driver does so, then starts screaming in excitement like a raving lunatic. What is VW's message here? To me, it says "Drive our cars, and you too will lose all sensibilities, scream like an idiot and make a fool of yourself."

Another fine example is the cereal commercial showing a guy munching on a bowl at his office desk while he gets fired (and the follow-up where he gets fired again, and again, and again), but can't hear his boss because the cereal crunches too loud. Message? "Eat our cereal and you will become oblivious to the world, so stupid that you will be fired from your job and not even realize it."

Now you'd think that companies would want to portray their customers in a positive light, rather than show blathering idiots as the kinds of folks who use their products. I dunno, maybe that's why I'm not in marketting.
