Your car is equipped with an automatic start-stop system. What is the environmental protection benefit from using this vehicle system?

You chose both fuel consumption and noise pollution, which are correct. An automatic start-stop system automatically switches off the engine when the car is stopped, for example at a traffic light, and restarts it when you want to drive off. This reduces fuel consumption because the engine doesn't idle unnecessarily, and it lowers noise pollution since the engine is off and therefore quieter during stops. Tyre wear is not affected by this system, so that is not a correct answer. Remember, start-stop systems mainly help save fuel and reduce noise when the vehicle is not moving.
