The amount of mistakes Google makes in the Netherlands when it comes to bikes is mind-blowing. If you don't know the area or manually check the maps it takes you trough a lot more car places that it should do.
Routing me through a park in the middle of the night, when it was closed, was one. Taking me on a detour to avoid a busy road, which turned to be on a farm track where the road surface was completely destroyed, was another.
