If you've ever thought that fast food wasn't fast enough, then it looks like McDonald's latest initiative has you covered. The takeout chain has begun trialling mobile ordering at restaurants in Monterey and Salinas, California. Hungry patrons will now be able to select their meal on the way to their nearest location for instant collection. The app will even use your GPS data to determine when your burgers start getting cooked, ensuring your food stays warm and fresh. When you arrive, you just pay through the app and grab that famous brown bag from the counter, drive-thru or curbside collection point.
