Sometimes it's hard to find the right direction to go on the road, even though the pavement is smooth enough that riding is easy.
Then a marker appears. This is a lane. But is it heading the right way?
Sometimes the directional hints seem to be correct but not clear. Is this path worn out? Was it meant for someone else?
At other times the signs are well defined but confusing.
But now and again the markers are completely unambiguous: Yes, this is your path. Keep going this way.
