There's a short road in Altrincham which has effectively been a one way street for cars and a two way one for bikes for years. A No Entry sign at one end stops vehicles entering at one end, but at the same end is a small, separate cycle lane which bypasses the No Entry restriction. The road is a narrow residential one, which is always clogged with parked cars on both sides leaving a narrow lane down the middle.
When I cycle the 'wrong' way down it and cars have to wait for me to pass I'm often told by irate drivers that the street is one way despite the absence of any signs to that effect, and some even take my photo on their phones so they can 'report' me.
