The cities contain many computer-controlled cars, all of which obey basic traffic laws, such as keeping below a set speed limit, stopping at the working traffic lights, moving out of the way of obstacles such as roadworks, and attempting to avoid head-on collisions with the player.
These cities host numerous automated vehicles that follow fundamental traffic guidelines, such as maintaining a predetermined speed, halting at operational intersections, yielding to hazards like road construction, and trying to avoid head-on crashes with the player's vehicle.
