One thought on “Interesting State Machines”

  1. In the US, we have “rest stops” and “truck stops” on major public highways. A rest stop has bathrooms, drinking water, maps, and maybe vending machines. A truck stop was originally for people driving semis, they not only had bathrooms but showers, diesel fuel, and sit-down restaurants. Rest stops slowly evolved in to something like a truck stop for people making long distance trips by car. When I drive from Pittsburgh to Philadelphia, I always stop at the same two rest stops to stretch, get coffee, etc.
