您可以尝试以下方法来生成所需数量的汽车，并将其设置为自动驾驶仪：

for i in range(number_of_vehicles):
        vehicle_bp = random.choice(blueprint_library.filter('vehicle'))
        npc = world.try_spawn_actor(vehicle_bp, random.choice(spawn_points))
        if npc:
            npc.set_autopilot(True)
            print("Vehicle spawned.")
        else:
            print("Vehicle could not be spawned.")
