Car commercials always have people driving on empty roads. I guess the idea is that the car in question will set you free from the normal constrainst of society. Anyway, I wonder if, when the commercial film crew shuts down the roads for filming, they are causing all the damn traffic jams. I don't actually wonder this, mind you, but there are a lot of car commercials.
