One horsepower formula fiction on a subject that always has a certain amount of go-power with boys. It concerns a hot rodders club that flings itself into a cooperative safety effort with the police. To help reduce serious accidents, the boys patrol on weekends, reporting all traffic violations they can spot. Hot rod clubs have done this and it's a potentially interesting situation. What wrecks this is the eager-beaver ""Yes, Sir/No, Sir"" relationship of the boys to adults, their stiff and uninspired dialogue in conversation with each other, and a robbery mystery solved by the patrol. Only one boy had held out when the club decided to take over the patrolling project and anybody who can tell a sprocket from a hole in the gas tank should be able to spot him immediately as a Bad Attitude driving badly straight to a bad end.
