What do you call the pedestrian friendly flat concrete down the middle of a road, with one lane of traffic going one way and the other lane of traffic going the other - a middlewalk?It's a motherfucking WALKway on the SIDE of the road, sidewalk makes perfect sense. Pavement could be the road itself, a patio, basketball court or a sidewalk. Think about it this way, you tell your friend you'll meet him on the pavement at 5:00pm. The poor sonofabitch thinks you mean the middle of the road and gets run over by a car and killed. Now you have a dead friend, how does that make you feel?
Lives will be saved by saying sidewalk.
