I don't know about that. But what I usually observe is that many people tend to veer off in the next lane in the direction of the turn (even if it's a lane for traffic going the opposite way!) if there is one. But if there isn't (right turn, they're in the rightmost lane), they'll tend to leave quite a lot of space between the car and the shoulder.

So I'd say these people have a hard time figuring out the space on the road their car takes. I can only imagine this worsens with larger cars and less visibility.

Oddly enough I recently accepted an old beat up, but gigantic utility truck from the 90s that I'd never have purchased, and while it's fun to drive, it's also absurd to try and park it anywhere. Even box trucks are comparatively easy to figure out. When it dies, I'm sure as hell not going buy another one, but until then I'll enjoy not knowing how close I am to anything.
