DIY Door Zone Warning
Seems not all Portland, OR cyclists blindly subscribe to the government line on bike lane door zones. Some safety-conscious cyclists have made the point rather clearly and shared it with their fellow cyclists exactly where and when they need to see it (what social marketers call an “interrupt”).
I think the graphic could be a bit more clear by adding a dashed line to the left; adding “CYCLISTS KEEP OUT” would be even better (though that gets to be an unwieldy stencil).
Fortunately this bike lane is wide enough that one can keep out of the door zone without leaving the lane. The same cannot be said for the ones in Baldwin Park. One would need to stencil the full width of those.
This photo reminds me of a story (perhaps apocryphal) of the cyclists who hijacked a striping machine in some major eastern city and striped bike lanes in the middle of the night. While many readers of this blog would disagree with that strategy from either legal and/or vehicular cycling principles, it speaks to a method of encouraging governments to address an issue.
