Where ratings tie, the location with more reviews wins. The pool is restricted to the LLM-classified car-wash formats that actually wash vehicles on site — Express Tunnel, Full Service, In-Bay Automatic, Self-Serve Bay and Hand Wash — so that detailing/tint shops, car dealerships and gas stations with attached washes don't crowd out the actual car-wash operators.
