The [[vehicle.carWanderRandomly|vehicle.carWanderRandomly]] function has the same functionality in the 3D universe games (GTA III, Vice City, and San Andreas). The extra driving parameters for those games can be set with [[vehicle.setDrivingStyle|vehicle.setDrivingStyle]] and [[vehicle.setCarCruiseSpeed|vehicle.setCarCruiseSpeed]]

// let this car drive around
