Taco Bell’s foray into AI-powered drive-thrus has hit a few unexpected potholes—mostly in the form of prank orders and cranky customers. After rolling out its AI voice assistant to over 500 locations, some diners took the opportunity to put the tech through the wringer, posting videos of themselves ordering things like 18,000 water cups just to see what would happen. Not surprisingly, frustration has also bubbled up on social media, prompting Taco Bell’s technology lead, Dane Mathews, to pump the brakes and rethink the rollout strategy.
Mathews admits the system works in theory—but not always in traffic. While the AI shows promise, it doesn’t always hold up under pressure, particularly in high-volume, busy drive-thru locations. That’s led the brand to reconsider where and how the assistants should be deployed. Learning on the fly seems to be part of the plan, though Mathews says the company is still committed to testing and improving the tech.
Taco Bell isn’t alone on this route—McDonald’s, Wendy’s, and White Castle are also steering into similar territory with voice AI. But deploying automation in a fast-paced, real-world environment is proving to be more complicated than scripting a chatbot. If brands want to speed up service without sacrificing sanity, real-time data and smarter deployment models are key.
