Congrats, fast-food chains – you tried to make drive-thrus smarter with A.I., and somehow made them dumber.
According to the latest annual Drive-Thru Study from Intouch Insight, the average fast-food drive-thru experience lasts a little longer than it did a year ago. We’re now clocking in at 5 minutes 35 seconds per visit, or nine seconds slower than last year. That may not sound like much, but when your french-fry-fueled serotonin levels are crashing, it’s a lifetime.
To be fair, they added more chains to their study this time around. If you only look at the ones they tested last year, the average drive-thru time was actually flat – or technically 3 seconds faster than it was in 2024.
Taco Bell has the fastest drive-thru
Taco Bell took the crown for fastest service, at just 4 minutes 16 seconds. Probably helps that every single item is some variation of a tortilla and cheese. KFC, Tim Hortons, and Arby’s weren’t far behind, keeping things moving and the curly fries flowing.
Chick-fil-A had the longest wait times at over 7 minutes. But before you cancel your waffle fry plans, there’s a good reason for that wait. They also had much busier lines, and still managed to rank first in friendliness and customer satisfaction. So yes, it takes longer. But Chick-fil-A customers feel it’s a worthwhile wait.
Burger King and Wendy’s are the most accurate
As for order accuracy, Burger King and Wendy’s tied for first among non-coffee chains, both hitting 88% accuracy. (Am I the only one who thinks that’s pathetic? The best of the best still get 1 in 9 orders wrong?)
The most common flubs overall? “Ice” issues, like ignoring requests for “no ice” or adding too much of it. Next on the list was forgetting an item or giving customers the wrong food.
A.I. screwed up more orders
When drive-thru A.I.’s worked as intended, they did make things go a little quicker. The problem is they’re still not as good at asking “would you like fries with that” as the average 16-year-old employee who does it while scrolling TikTok.
Drive-thrus using A.I. were less accurate, getting orders right just 83% of the time. That’s lower than the overall industry average of 87%.
One in every three customers also had to repeat themselves to A.I., and a human had to take over 21% of the time.
