The city of Anyburg decides its traffic situation has gotten out of hand, so it puts the automobile on trial. The trial (conducted in rhyme) starts with a car that was in a hit-and-run accident, followed by a sports car whose sins are peeling rubber and general hot-rodding, followed by a heap, on trial for lack of safety. Next, a number of safety equipment designers testify that, despite their best efforts, the accident rate keeps rising. Through all this, the defense lawyer declines to ask questions. A highway designer bemoans the problems on his beautiful roads. At last, defense. He shows a number of scenarios, pointing out that the real problem isn't the car but the driver. Everyone left the courtroom, declaring the car not guilty, and drove politely again, for a little while.
