^ Right on!I know you think that's true and it is certainly intuitive, but on a 4-lane road it works everywhere I have tried it. It also works on 2-lane roads when traffic is light enough that cars behind you can pass, or if you pay attention to them coming up on you and move over to let them by. It wouldn't seem that moving over to let them by and just riding to the right would be any different, but it is. The act of making them take note of you then letting them by just seems to create a better relationship between the car and the bike. The car can't blindly just squeeze past without taking note of the bike. The whole process becomes conscious. As far as riding 2-lane roads when traffic is heavy and you will be alongside cars in a tight space for extended periods of time, I have to say that isn't very safe anywhere. There have to be better times and places to ride.
By the way Houston has just enacted a 3-foot clearance rule for motor vehicles passing bikes. First positive law for cyclists in these parts anyone can remember.
