Why Gas Stations Cluster on the Same Corner — Game Theory in Real Life

Ever notice how gas stations, coffee shops, and fast-food restaurants tend to cluster together rather than spread out evenly? Your first instinct might be that this is irrational — wouldn't they sell more if they were the only option in their area? But game theory explains why clustering is actually the optimal strategy.

This is called Hotelling's Law, named after economist Harold Hotelling who modeled it in 1929. Imagine a beach with two ice cream vendors. If they split the beach evenly, each takes half the customers. But the vendor on the left can steal some of the right vendor's customers by moving toward the center. The right vendor responds by moving center too. The equilibrium? Both vendors end up right next to each other in the middle — the same outcome you see with gas stations.

The principle extends far beyond physical locations. It explains why political parties converge toward the center during elections (moving toward the median voter), why major brands' products look increasingly similar, and why streaming services all seem to produce the same types of shows. Competition doesn't always produce diversity — it often produces convergence. The game theory math shows that differentiating is risky, while copying your competitor's position is safe.
