Concrete Pyramids

Miami Dade has legalized concrete pyramid use on swales in 2018 I believe. But what about fort Lauderdale? Is it still illegal or depends on the area? I have a neighbor who has a nurse picked up every day and the driver always goes over our grass area to park in front of their house (on the swale) to pick up the nurse. We used those sticks that have a reflective red circle for caution and they have been driven over. They have plenty of space to park in the parallel way but they decide to drive over our grass.
