I remember doing that as a child.LakePlay, for the past 15+ yrs, there was a Federal Law instituted which mandated all vehicles be equiped with a shift interlock system which requires that the brake pedal be engaged before the shifter can be moved out of park. This reqirement was imposed on all vehicle manufacturers selling vehicles in the U.S., because of many instances where unattended children were able to set the vehicle in motion simply by moving the selector lever.
