"The Speeders" by Arthur Tofte: In the world of the future, the government has supposedly ensured that vehicles will be safe--no speeding and no accidents. But there are always the young joyriders who will find their way around the laws and restrictions. These young men find that when thy joyride and manage to break the speeding laws one too many times that they are incarcerated--not in prison, but in Traverse Park. In what seems like a speed-demon's paradise, all bets are off. The speeders can go as fast as they want and drive as recklessly as they want. Is it really the freedom from restrictions that it appears? Or is there a more chilling motive behind the speeder's park?
