I hope that the ones for cars are actually accurate, unlike the pedestrian ones which drastically underestimate the time, causing people to ignore it completely and just look both ways.
Well... the seconds are appropriately long, there just aren't enough of them, so there's plenty of time left to cross after 0. Or maybe it's just Porter Square's weirdness, to go along with the striped sidewalks and windmill and boulders...
