Okay. I live on a one-way street. It’s been one-way since 1956. The proper flow of traffic is south to north. Parking is permitted on both sides of the street. At the north end of the street, there are four signs: two one-way signs and two Do-not-enter signs. About 15 feet up, facing north, are two, large red “WRONG WAY” signs. I am continually amazed at the number of people who manage to miss the “NO LEFT TURN,” “ONE WAY”, “DO NOT ENTER”, and “WRONG WAY” signs and drive (usually quite fast) the wrong way on the street. Apparently, they don’t notice or care that all the cars are parked FACING THEM. That really should clue them in.
