Just yesterday I see drove onto a Google Maps recommended muddy dirt road road (like a dumbass) with my rental car just in the Mexican jungle. I thought I could make it, until I couldn’t. I got stuck in mud about 5km, walked through mud to the highway, and learned all about hitchhiking in Mexico, and asking locals for help getting my car unstuck. Good times.
Reading through this whole discussion thread it looks like the pattern is that Google Maps data is super sketch for anywhere that's not the continental US.
In September, I was in Hunza, northern Pakistan. The mountains are so tall, like 7k to 8k+ meters tall, I couldn’t even get a GPS lock most of the time. Even with a downloaded, offline map, it Google Maps was less than useless for navigation (still worked OK as a “paper” map).
