There’s more than one reason why someone might park against their own curb cut.
I am unable to access my driveway at least several times a week because of people parking at least halfway across the curb cut, or sometimes (every day for the last two weeks, for example) actually parking IN the driveway. If I can see that there’s a half car space left, which means someone will park there and block the driveway, or a truck/van for service work double-parked nearby, I will park against my own curb cut to keep it from being blocked.
Since no one ever gets a ticket, even if 911 is called, I’m secure in the knowledge that I’m not risking one either.
I’m not doing this because I’m a jerk, or entitled. I’m doing this because other people are entitled jerks, and the police enable their behavior by not doing their job.
