After dark in the rain...
If I find myself out after dark in the rain (which is often in the Winter months here in Oregon) I will filter to the front for safety reasons. I have never had a problem with LEO's or other road users.
In the daylight people seem to get pissed off.
Always be ready to split lanes to escape.
