One time on a very long road trip across Canada, Apple Maps decided to route me two hours north of the main highway on a smaller (but paved) highway, and then across a 200km long gravel backroad, back to the main highway. I had been driving for about 10 hours at the point and didn't really notice until it told me to turn onto the gravel road. It's pretty much the only time I was afraid I'd be stranded in the middle of nowhere, since I was on about a quarter tank of gas at that point and out of cell service, so I was unsure if going back to the main highway or across the backroad would be closer to a gas station. In the end I took the backroad and ended up just making it after driving on the "empty tank" light for about 80km (which is surprising how long it lasted!). My fault for zoning out and blindly trusting GPS!
