Firestone PD will park a vehicle during the evening, sometimes a low-vis Chevy with no lightbar, on Tipple facing Silver Birch. That unit will poll traffic with lidar as it approaches, and also nail cars for rolling stops at the fairly new four-way stop there. Firestone is known to be very aggressive with its speed enforcement, even when dealing with people who live in Firestone, and will light vehicles up for as little as five over or not coming to a full, three-second stop.
