Every pick up and drop off there is a parent arriving in a car. There is huge clouds of black smoke coming out of the exhaust, they leave the engine running for ages whilst waiting for the gates to open and when they set off again they drive so fast and revving the engine when there is children crossing roads. Would you report this to the school or is there something else that can be done? The school is always trying to promote less fumes and walking instead of travelling by car and to turn engines off whilst waiting etc
