No, but assuming everyone in those cars is capable of walking is equally implausible. I have a mother who's wheelchair bound and wanted to see the cherry blossoms so I drove her around. Does that make me a carbrain?

I grew up in DC in a part of town with no metro service and crappy bus service. Driving became de rigueur. Once you learn to navigate the backstreets and avoid the choke points DC is not that bad of a driving city.

Or its being used to chauffer someone who can't walk or ride a bike, and would have a hard time utilizing public transit. Because it's peak smug jackass to assume everyone who uses a car is too lazy to walk.

Or, like me, your driving an elderly relative who can't walk anymore to see them. When you assume you make an ass out of you and me.

As a former DC government employee who worked on this kind of thing in the mayors office, the NPS will do whatever the fuck it pleases with or without input from the DC government.

Well calling them a customer doesn't feel right either. Basically it seemed like the most neutral term choice.

The problem your having is that some people are assholes. I used to work for parking enforcement. So long as a citizen wasn't overly rude or disrespectful of me I'd do my best to help them navigate the complexities of the system. Whereas I had at least one coworker who fucking delighted in torturing people for no fucking reason other than she could (she's dead now, after suffering for a few years with a stroke, so karma is a bitch).
