At the McD's nearest me, they will start when I'm at the nearest stop light; if I get stuck on a long red, timing is pretty good. At other locations, starting in the parking lot is still a little faster than if I had ordered in the store; drive through may be faster from the parking lot, but if the queue is full to the order point, if I order at the regular point, my order is usually ready by the time the orders in front have been taken care of; the order point is usually placed so the pipeline works smoothly at peak volume.
