TONE DEAF. Cadillac's latest slab-sided sedans are butt-ugly. Now comes a television commercial to suit the car. A silver sedan backs into the tunnel. I'm not sure whether what comes next is the firing up of a linear induction motor or the firing of a pistol, but the sedan departs the tunnel at some great velocity.

What's the message, that the owner can simultaneously demonstrate a lack of aesthetics and a surfeit of road rage?
