If you're the type of driver who doesn't think twice about parking in the bike lane, your car might get bombed with an "I Parked in a Bike Lane" sticker, which a group of guerrilla cycling advocates hope will help to curb this unfortunate and quite frankly dangerous behaviour. The Instagram account affiliated with the stickers has been up and running since late August, and while it doesn't boast too many photos, spottings have been frequent enough on social media with the tag #IParkedInaBikeLane.

The best part, if you're into these sorts of things, is that the people behind the sticker campaign will send interested parties their own set so they can tag perpetrators as they see them and then post the evidence to social media. It's a clever way to leverage the crowd in a sort of mass shaming ritual. Will it work? That's another story. I suspect some people would be mortified to make an appearance with the sticker while others would just shrug it off. Either way, I expect this tactic to get plenty of attention.
