San Francisco: Parking Signs
Pay or die
So imagine you're a civil engineer, or human interface guy, or something that just doesn't like seeing stupid things. And you stumble across this.
Well about every 40' is one of these pay stations. So they're virtually everywhere. You can see the next one from the current one, so there's no need for the intermediate sign or two between them. But let's pretend there was.
In the end, I don't care what stupid things a city does. I only visit SF nearly weekly. But there's so many dumb things they do, you have to wonder about all of the IQ's of SF city workers. So it's not any one dumb thing, it's sort of all of them together. The best way to put up a parking sign seems to be the least of it. But still hints and the degree of dumbfuckery that is the bay area.
