Last year I was driving on an arterial, with a 35mph speed limit, that was a miles long downhill grade. There was a bike lane on the right. In it was a girl maybe 12, and on the back of it was another girl maybe 6. With the downhill, she was able to go about 20mph. Suddenly, she veers into the center of the car lane. Never looked over her shoulder. (Traffic was lining up behind me.) She then rides a bit on the stripe separating the bike land from the car lane. Then back to center of the car lane. Then in the bike lane, then back to the car lane. Back and forth. She never looked over her shoulder. I never dared to pass her, even when she was in the bike lane.

OMG
