Fascinating observation. I doubt there is a mechanical link to your location but my guess is your driving habits are such that this location is the place your evap monitor drive cycle completes, hence popping the code. There are several conditions that will stop the cycle including speed over 100 kmh, full/empty tank, AC on, sudden throttle application.invomplete warm up, warm start.es. As an interesting aside, the evap code always tends to come on when I pass through one particular section of a town.
..or its cognitive bias, which you can cleanse with some stuff you can buy from the Internet .....
