Before even getting into the episode, I must complain about the episode art: The highway sign says “ROUTE” and has the shape of a US Highway shield (which is often called “route”, so that’s correct), but is then colored like an Interstate Highway shield, which is a very different system and should not be confused (US (and state) routes are basically just normal roads, just higher priority, and Interstate highways are major controlled-access thoroughfares with much stricter design standards)
