It’s not a major problem, but from some reason they (Mexicans) bicycle approaching traffic, which is the way it’s done in Mexico, but not in America. This endangers the cyclist as the amount of time between perception and action is dramatically reduced for both parties, which means that they have less time to avoid each other. It’s particularly bad at night. Also the Tullock Effect is reduced as avoidance is not the clear responsibility of either party.
I saw three people doing it yesterday.
