My recent experience with new Google Maps shows that it constantly leads me against traffic on a one-way streets in Europe in general and in Poland (where I live) in particular.
Are there any laws or regulations for this?
I assume Google wouldn't set a track that would violate local laws. But, on the other hand, it seems quite unnatural for me to bike against traffic on a one-way street.
And recently I have found a typical one-way street with a typical one-way signs on both ends:
And each sign was additionally labelled with a special label saying "Bikes excluded", which would suggest that biking against traffic on a one-way streets is strictly prohibited unless otherwise stated.
