I’ve been spending a lot of time in Mexico City. I had to abandon Google Maps there. The transit system has an excellent metro, a solid BRT setup, some electric tram buses that are fine and then the purple buses that run irregular routes, don’t always accept the transit card that the rest of the system uses, and are by far the most unsafe option, such that even locals won’t ride them unless they have no choice.

Google will always route me on the purple buses. Even when the metro is faster. Their directions in Mexico City make zero sense.
