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.

Sure. It's definitely in the "a little." But given how slow the kiosks and apps are to operate, due to all the animations and cross-platform frameworks, getting that order done before you get in the car to go means the order starts when you pull into the parking lot, rather than after you go inside and poke buttons on the kiosk 37 times.

Or in the slim chance that there is a line it's good. But I've rarely seen a number of kiosks insufficient to prevent lines.

They only changed this recently.
