Perhaps we should focus our attention towards getting the police to issue citations for drivers that interfere with bike lanes. I have more than once watched a driver block the bike lane in plan sight of an officer and seen nothing done about it.
Is it illegal in Portland to block or "interfere with" a bike lane? What if you're entering a driveway, and there is a holdup in the parking lot you're entering, and you have to stop as you're entering the driveway, thus blocking the bike lane? That would annoy a lot of cyclists who are uncomfortable with having to leave the perceived safety of the bike lane to get around him, but is it illegal? What about opening a door in a door zone bike lane? Of course it's illegal to do it when that would cause a cyclist to crash, but say he's a half a block down, and it takes you a minute to get the kid out, so by the time he gets there, the door is still open blocking the bike lane? Is that illegal?
In CA it is legal to park in bike lanes unless there is an explicit no parking sign.
So why the big deal about blocking bike lanes? Normal traffic lanes are blocked all the time. In general, if you have to block a street, you're supposed to do it "as far right as practicable". Well, that's often the bike lane. What's the problem?
Where does this notion that motorists are not supposed to "interfere" with bike lanes come from?
