I want to say Michael Moore did an experiment in NYC. It may have just been one of the networks. They put out a bike rake in the middle of the city with a sign saying, “public bikes: take one, just bring it back”. No one touched the bikes all day. Then at about 2 in the morning, a large U-Haul pulled up and 3 guys start putting all of the bikes in the back! Luckily, it was all on video for the police.
