The pushback to describing it as "loop around" is that it implies it adds extra time to a pickup vs parking on the shoulder, and it doesn't. It adds an extra minute to stopping, but once in the lot there is little to no difference in pickup times. The "loop around" only matters if someone for some reason was driving nonstop through the lot to go to arrivals, which Uber and Lyft drivers do have to do in order to access the the commercial road from where they make pickups, but they don't have a choicr tomdo what they need to do. However, if you are coming early to pick someone up, there is virtually no difference between sitting in the lot vs sitting on the shoulder, except one is legal and had vending machines and the other is illegal and dangerous. One caveat is if parked on the bridge shoulder, which is even worse but thankfully most cars are not parked there. Other caveat is of there is traffic on the arrivals road from the lot.
