Casey Neistat got a ticket for riding his bicycle outside of a bike lane in New York City. He argued with the police officer that sometimes he does so because there are obstructions that make it unsafe to use the designated lane. The cop didn't care, and issued him the citation anyway. To prove his point, Mr. Neistat made this video, showing how dangerous it would be to comply with the law...by crashing his bike, over and over again into road hazards. He saved the best for last. via reddit
I also don't understand how he was pulled over, just turn around and ride away.
Shemp: "Ride in the bike lane! Get off and walk the bike around the obstacles. What's so hard to understand about it?"
So when there's an obstacle (say, a broken down car or some construction) in front of you, and a double-yellow line on the road, will you just stay there forever?
No, you won't, and you don't even have to. Just as the rider can leave the bike lane to avoid obstacles.
