My rides from midnight to about 4:30/5:00AM I have the entire road most of the time otherwise a couple of feet from the right. In designated bike lanes usually in the middle.
Coming home from drug store yesterday on 45mph road with 2 lanes each direction and bicycle lane I constantly checked mirror and one time had a car come 1/2 way into the bike lane when it was 200' behind then thankfully moved out and over the hashed line as it passed and proceeded to cross back over the solid white line into the bike lane about 100' after passing
