Florida has a ton of Chargers,Tahoe's [but not a lot of Tahoe's] a lot of Explorer Utilities. The city of Miami has a ton of Taurus Interceptor sedans. In Miami-Dade the past couple of months seeing Durango mixed into the fleet of Chargers and Taurus sedans.
When I recently drove from Jacksonville to Miami saw FHP mostly with brand new Chargers and only a sprinkling of Tahoe's. Also saw FHP with a few new Black F-150's. They seem to be using the F 150 for Commercial Enforcement.
Jacksonville used the Impala for years. Miami had some Impalas but they mostly bought the CVPI until they stopped making them.
