Drive-Thru AI Stumbles in the US: Lessons for India's QSR Boom
McDonald's killed its IBM tie-up. Taco Bell is rethinking it. Only 4% of Americans want AI taking their drive-thru order, says YouGov. For India's QSR pipeline, that signal matters.
The News
McDonald's killed its voice-AI drive-thru partnership with IBM in 2024. A year on, Taco Bell's chief digital officer Dane Mathews told The Wall Street Journal the chain is reassessing its own roll-out after customers trolled the system by ordering 18,000 water cups. The Securities and Exchange Commission has charged Presto, the AI vendor behind chatbots at Checkers, Rally's, Carl's Jr., Hardee's and Dairy Queen, with misleading investors about what its software could actually do. A 2023 SEC filing showed that workers in the Philippines were handling most of the orders the AI was supposed to be taking.
The retreat comes from a confident start. McDonald's first deployed voice ordering at 10 Chicago locations in 2021, built on its 2019 acquisition of Apprente. Wendy's followed in 2023 with "FreshAI" in Columbus, Ohio, built with Google, and later claimed to handle 86 percent of orders without human intervention. Taco Bell had pencilled in hundreds of US locations by end-2024. A January 2025 YouGov survey found only 4 percent of Americans would prefer an AI to take their drive-thru order; 55 percent prefer a human.
Why It Matters
Voice AI at the drive-thru is the first large consumer-facing deployment of conversational AI to hit a real ceiling. It is not a language-model problem - the same underlying tech serves billions of ChatGPT queries cleanly. It is a failure of the operating envelope: regional accents, ambient noise, menu drift, and a customer who can simply order 18,000 water cups to break the script.
The last time a customer-facing AI product unravelled this publicly was Amazon's "Just Walk Out" stores, reportedly leaning on more than 1,000 manual reviewers in India. Presto's Filipino backstop is the same script with a different cast. When humans are still cleaning AI output, the unit economics do not work, and chains retreat to lower-visibility uses: kitchen prep, inventory, menu boards. Burger King is already there with "Patty," a headset assistant that listens for whether workers say "please" and "thank you."
Indian Angle
The Indian QSR pipeline is watching. Jubilant FoodWorks (Domino's India), Westlife Foodworld (McDonald's West and South India), Sapphire Foods and Devyani International (Yum!'s KFC and Pizza Hut franchisees in India) are the obvious deployment surface for Indian conversational-AI vendors such as Yellow.ai, Slang Labs and Saarthi.ai. But India's order surface is delivery-led, not drive-thru: Zomato and Swiggy carry most QSR volume, so the highest-value Indian deployment of voice AI in food is probably inside an aggregator's complaint flow or a kitchen's ticket queue, not at a window.
There is a second point for India's BPO industry. The Presto case frames undisclosed human-in-the-loop work as a securities issue, not just a labour one. Indian and Filipino vendors that backstop US AI products now have a new compliance vector to think about, and listed Indian IT-services firms selling AI-augmented offerings should expect investor questions about how much of the "AI" in their margins is really people.
MeitY's IndiaAI Mission has earmarked roughly Rs 10,000 crore over five years, most of it for compute and foundational-model work. The drive-thru story is, at its core, an evaluation failure: bots passed internal QA and broke in the field. A voice deployment that must handle 22 official languages and constant code-switching will fail harder unless evaluation gets its own dedicated budget.
FAQ
Has any Indian QSR confirmed an AI drive-thru rollout?
No major chain has announced a public deployment in India. The dominant ordering surface remains app and aggregator-driven, so the early Indian use cases are more likely to surface in call centres and kitchen displays than at the drive-thru window.
Why did McDonald's end its IBM partnership in 2024?
McDonald's has not given a full public explanation, but order-accuracy complaints and viral social clips of bungled orders preceded the wind-down. The company has since said it is exploring AI for kitchen-equipment failure prediction and weight-based bag checks.
What did the SEC actually charge Presto with?
Misrepresenting the capabilities of its AI drive-thru product to investors. A 2023 filing revealed that staff, largely in the Philippines, handled most of the orders the system was being marketed as automating.
