And remember, the less educated motorists will think you should remain in the bike lane no matter what -- not being cyclists themselves, they don't understand the dooring problem or other issues that cyclists have w/ the bike lane -- so expect some idiot motorists to verbally harass any time you leave the bike lane for whatever reason...
