Once I was directed my Google Maps in Germany leading to a closed entrance of a highway. I passed that entrance and Google rerouted me, after driving for some time apparently I went through a big loop and go back to the same entrance. Then I drove off to the other direction, somehow I went back to the same entrance again, passing through a certain road that we already remembered from the last loop in the opposite direction.

We wasted what feels like an hour, but probably around half? And then we changed to Apple Maps which has the data on the closure and we can get on the right road on the first try.
