Very few people are using personal AI agents to order Ubers, apparently. On the transportation giant’s third-quarter earnings call on Wednesday, the company said that only four rides were ordered through an AI agent during its busiest week in October: the week of Halloween.

While more people used an AI agent to order food through its delivery service, Uber Eats, the volume was still fairly small compared to the overall number of trips.

Uber’s chief financial officer, Balaji Krishnamurthy, told Wall Street analysts on the call that the company handled around 320 million trips and orders across Uber and Uber Eats during the week of Halloween, but only 500 Uber Eats orders were placed by an AI agent.
