Google Maps once sent me into a gigantic snow bank approaching a mountain pass. It was right around this time of year, so I guess their historical data assumed the pass was open. I came around a bend and, that’s where the plows had stopped maintaining the road.

I was fortunate to get some help getting my car out from locals who were driving around the area, and when I stopped in the nearest town for lunch everyone knew the pass was closed. But I had to reroute my whole trip to freeways to get GM to stop trying to send me back over that pass.

There were no dotted lines. There was no way to tell the app that route was impossible.
