McDonald's wants to improve drive-thru speeds -- to help customers, of course, but also in hopes of getting them to show up more often and spend more when they visit. It's the latest move by the fast-food giant in using technology such as artificial intelligence and the introduction of "meat" created from plant protein to drive more business. Earlier this week, the chain unveiled its plans for a better drive-thru experience during an investor update. It's testing express lines for people who place digital orders ahead of time, as well as dedicated pickup spots and automated ordering. The drive-thru has become even more important for restaurant chains during the pandemic, when people want to avoid dining rooms and prefer contactless payment.
