I contend it does. People tend to take way more time backing into a space than pulling into it, and hardly more time backing out of a space than pulling forward out of it.
I'm certain this isn't how they think of it, but when I see someone blocking traffic while they painfully back into a spot, I imagine them imagining themselves having to fly out of there without a moment to spare, like they plan on having a drastic emergency before they leave. And if that person isn't driving a police or fire department car or the like, I roll my eyes at the delusion of grandeur.
Surely a big part of the reason is steering leverage relative to the kerb.
You are able to one-shot reverse parallel park into a much narrower gap without hitting the bumpers of the cars around you or getting onto the pavement.
