I’m not going to take a stand one way or the other on the Dangers of Mexico debate. In my opinion though, it’s as dangerous as you make it.
Here’s an example: Wherever you live, can you ride your scooter downtown, park it on the sidewalk, put your helmet on the floorboard, hang your purse on the handlebars with stuff sticking out of it, and just walk away?
Didn’t think so. And no, the owner was not anywhere in sight. I stood there for a few minutes dumbstruck, looking around, while people just walked by.
