I not necessarily disagreeing with you, @Mustangman, but I have observed the same line-hugging/flirting with traffic behavior in other situations where there is no grass involved. Specifically, I am referring to left turn lanes on busy streets and highways.
In my town, there is a wide avenue--complete with dividers between northbound and southbound lanes--that has a few left turn lanes that are controlled by traffic lights. When I am in one of those left turn lanes, I stop as close as possible to the divider to my left, in order to be as far as possible from the traffic that is zooming along in the left travel lane at ~50 mph. However, I always observe that a substantial percentage of the other drivers in the left turn lane will stop their cars--literally--only a few inches from the traffic in the left travel lane, while leaving a couple of feet between their car and the center divider.
I'm sure that this has to do with ignorance, but how can one ignore the reality that some of the drivers in that left travel lane might not be paying full attention and could wind up hitting the car of the ignorant driver in the left turn lane who is sitting only a couple of inches away?
Why would somebody NOT place his stopped car as far as possible from moving traffic?
