Zoox CEO Aicha Evans agreed that autonomous vehicles should be regulated as the Amazon subsidiary’s fleet of autonomous vehicles launched its first paid service in the United States in Las Vegas Monday. 

In June, one of Zoox’s robotaxis drove into heavy smoke at an active emergency scene in Las Vegas. Zoox issued a software recall following the incident and has since updated the technology to better detect and respond to fire and smoke.

Evans told FOX Business host Liz Claman the company believes in transparency and taking responsibility.

“These are rare edge cases,” Evans told “The Claman Countdown” on Monday. “We learn and we continue to improve our processes along the way to make them better and better.”

“Sometimes it’s software, sometimes it is firmware, sometimes it is just using simulation,” she added. “We throw the best at it, we root cause, we learn, we improve and we deploy.”

Evans’ remarks come as federal officials press autonomous vehicle (AV) developers to improve interactions with first responders and emergency personnel, warning that failures to do so could pose a serious risk to public safety.

“To state it bluntly: an AV that cannot safely interact with first responders is a danger to the general public,” National Highway Traffic Safety Administration (NHTSA) Administrator Jonathan Morrison wrote in July.

Evans, who thanked Morrison for his partnership in advancing American innovation, said she believes autonomous vehicle regulation is necessary.

“I want to unequivocally say we agree with the administrator and the administration and the regulatory agency. We need to be regulated,” she said. “And EV scenes are extremely important, because it’s about saving lives all around.”

After providing free Zoox rides in Las Vegas since 2023 under a three-year pilot program, the Amazon robotaxi brand officially began charging customers for rides on Monday.

“We have essentially, so far, the same number as people who are taking free rides,” Evans told FOX Business.

Unlike competitors such as Waymo, which retrofits regular cars for driverless operations, Zoox’s vehicles are pedal-free, steering-wheel free and passenger-focused. The robotaxis feature face-to-face campfire-style seating for up to four passengers.

Roughly 65 Zoox are currently deployed in Las Vegas and Evans said production is “ramping up,” with the company’s California factory is doubling output to five to six vehicles per day.

The CEO also told FOX Business where the company could expand next, beyond Las Vegas, San Francisco, Austin and Miami, where Zoox currently operates pilot programs.

“We will be entering Atlanta and LA and… we have big ambitions,” Evans said. “We want to be everywhere where we are welcome and show and deliver these wonderful and lovable experiences to customers around the U.S.”
