Every year, without fail, I get at least one whole bus of Canadians coming up my driveway. On GPS, and many years ago it was one, it appears to be a road. It looks like a nice little shortcut up and over the mountain that brings you back in on another road that brings you back to the main road. The bus is full of Canadians looking at foliage. We'll get back to that...
There's a lot of roads here in Ontario like that, and without fail every year there a group of Americans following their GPS that go down it, and get stuck in 10" of mud. Haven't had problems with buses in ~15 years with the roads near here, but cars that's another problem. The tow trucks make a good bit of money pulling the cars out. The problem of course is that county maps marked them as passable roads...20 years or even 40 years ago. GPS makers just grab the maps and go on their way, they haven't been in use for at least that long. In some cases, the roads were built when they were laying pipelines and so on.
Get out in western Canada, where the roads have been moved and it's even better. You can see roads 200-800ft off where the GPS is and you'll get someone who drives off into the ditch.
As for getting the GPS map information changed? Good luck. The only solution around here with the worst cases is to string up a couple of steel poles in cement, drop 2 or 3 chains with either a chunk of yellow or orange tubing with reflectors on it. It was even worse when I was living up north, and you've got motorists who've followed their GPS and ended up 10-20 miles in the middle of no-where, and their cars are suddenly stuck in 20-30" of snow. Then you'd get the RCMP or OPP asking for people to go out and search, or simply call you up to go rescue them because they don't have anyone else that can do it. Occasionally their cars get left there for the winter, because no one is risking their truck or tractor to go pull it out.
