I've got this Bike Safety pamphlet I finally found again. Somerville police were recently handing these out, so I grabbed one. I love this section showing how to ride in a painted bike lane. It shows that if you ride too close to the cars, you can get doored (correct). So the diagram shows someone "safely" biking far to the left of the bike lane, one arm into the car travel lane (super dubious advice). The text explains all this, then adds that sometimes you should just bike in the road to stay safe (Yup).
It's pretty weird to see this admission that some of the bike lanes aren't safe for bikes, and you can/should just ignore them.
