I didn't draw the lines. Yet I follow mostly all of them, maneuvering carefully and dutifully along the way.
Still I have trouble keeping between them when I park. Sometimes I'm way over too far. Other occasion I'm right on the line. More often than not I have to back up at least once. Oh well, I'm good at backing up and I know how to drive on the left hand side of the road.
I don't know what that'll come in handy for but it should come in handy for something.
