It was on a tahoe trip to ski, we happened to hit a snowstorm that day. Apple Maps decided to optimize the route and suggested a better route through a friggin road that passed rather close to a ski station (could even look the name up).
We had a 4x4 and we were fine for the most part, but things got really bad when descending, started loosing traction and in one turn we actually slided and the snow stopped us on the edge of a cliff, not even exagerating.
To be 100% clear, this is entirely our fault. We should have been with chains from the very beginning. But it's still shocking to me Apple Maps would suggest such a freaking route in the middle of a snow storm. Would Gmaps have done the same? Probably?
Experience was bad enough to swear never open AMaps again.
