Car wash chains lead Interstate Batteries' top 10 neighbors — a cross-kind finding that says more about shared audience composition than about automotive overlap. Similarity here measures how closely two entities' audiences resemble each other in shape; a score of 0.79 means the audiences look nearly identical in structure, regardless of what the entities sell.
Club Carwash (0.79) and Tommy's Express Car Wash (0.78) sit at the top, both Car Wash and Detailing services — making them the dominant subcategory in the set. Below them, the neighbor mix spreads across a wide range of kinds: Flooring America (0.77) and Window World (0.76) represent home improvement retail; Red Lobster (0.75) and Steak 'n Shake (0.75) bring in casual and fast-casual dining; Indian Motorcycle (0.75) and J.D. Byrider (0.74) are the only other Automotive neighbors in the top 10. HobbyTown USA (0.73) and Kincaid Furniture (0.73) round out the set, representing hobbies retail and furniture respectively.
Only two neighbors — Indian Motorcycle and J.D. Byrider — share the Automotive category with Interstate Batteries, and neither shares its Maintenance and Repair Services subcategory. The top 10 is otherwise a broad mix of home goods, dining, and services, with no single subcategory dominating beyond car washes. The broad shape reflects an audience that doesn't cluster tightly around any one kind of entity — it overlaps widely across everyday consumer categories.
