Yeah, this. NYC issues ~$500 mil in parking tickets per year. If this were a rational issue, someone would look at that and say "Wow. We must be doing something wrong, this is way too many tickets written. Are the street signs clear enough?"

I'm kind of making fun, but they don't want to fix the problem because those tickets are a genuine revenue stream for the city. When the revenue from parking tickets goes down, everyone panics.
