[MrE]

You see the rear exit on the street to the left of your example? I have a similar intersection that I need to get over to make a u-turn, so I head for the furthest (away from the intersection) driveway to exit. I drop my daughter off at Math tutoring and see similar behavior as you describe. I just laugh as they are still sitting there waiting while I've already navigate over to the left lane to make my turn.
