I have a hypothesis that DoorDash drivers specifically avoid parking within lines because it quells their conscience a bit compared to parking within the line and not paying the meter.

Also, a lot of people insist on driving a car-and-a-half. In my opinion, these people should just be forced to pay for two spots like a fat person on a plane, but I'm not dictator of Pittsburgh yet.

And speaking of Doordash, all Pittsburgh or any other urbanized municipality would need to do to rake in ticket revenue would be to focus all of their ticketing efforts from 4-8 PM instead of randomly throughout the day (including residential streets near restaurants), but the workers are probably resistant to working evenings and I don't really think there's any political will to go after parking freeloaders because they're bRiNgInG tHeIr bUsInEsS.
