Superman Declares War On Reckless Drivers! Clark Kent finds a friend of his, Charlie Martin, has been hit by a reckless driver. As Superman, he busts into the studio of radio station WVUX and issues an warning: Homicidal drivers will have to answer to him!
He starts a many pronged attack on the causes of bad driving. He destroys all the impounded cars of traffic violators. He destroys unsafe used cars. He scares a drunk driver and a hit-and-run driver into changing their ways. He destroys the equipment of the Bates Motor Company, who made inferior cars that were involved in many accidents. He stops a police officer from taking a bribe. He straightens a road that has dangerous curves. Finally, he catches the mayor speeding and shows the mayor all the deaths he's responsible for by failing to enforce the traffic laws.
The next day, the editor of the Daily Star tells Clark Kent of the new reforms the mayor is introducing. As Kent goes to his car, he is given a ticket for parking in an improper place. While he's outwardly annoyed at the ticket, Kent is happy to see the law get enforced.
