Specifically the section: When (Not) to Split a Two-Way Road
In my opinion this road does not need to be split, as there is no gap at 100m zoom and no U-Turns are required that I can see. There was just a single turn restriction which was incorrect, so I went ahead and corrected it.
I went ahead and unlocked the segment anyway, and several other parking lot segments around as there's no reason for parking lot segments to be locked. The roads here could use quite a bit of junction work, as many of them seem to have reverse connectivity, etc. The Highlight and Node Fixer scripts can help you out here, and the bonus is they help the maps out and at the same time pull in points pretty fast. Keep "Show Connectivity Arrows" on while you do this, so you'll see any existing turn restrictions as you'll have to restore them when you fix a junction.
