You couldn’t swing a lanyard at CES for the latter half of the last decade without hitting a robotaxi; post-COVID, the number of startups has shrunk, but the technology has definitely matured. Go to the right cities—San Francisco and Austin, Texas, spring to mind—and you might see dozens of sensor-festooned vehicles among the downtown traffic.
The pod-like robotaxis belonging to Zoox stand out. Other robotaxi developers are retrofitting existing vehicles like Hyundai Ioniq 5s with sensors and the computing power necessary for self-driving. Zoox, which was bought by Amazon in 2020, did that with its test fleet, but as it starts to offer ride-hailing services—currently in Las Vegas and San Francisco—it’s doing so with a purpose-built design that looks like it just drove off the set of a big-budget sci-fi production.
“A robotaxi is not a car; it’s not a human-driven vehicle, and the requirements are wildly different, although it has to live in that world,” explained Chris Stoffel, director of robot industrial design and studio engineering at Zoox.
It all starts with the sensors, each perched on a little ledge projecting from the top four corners of the robotaxi’s body. From up there, each has an unobstructed, high-level view, giving the Zoox robotaxi good situational awareness, particularly straight ahead. “Because we don’t have a traditional hood, we’ve optimized our frontal coverage in a way that would be nearly impossible on a retrofitted vehicle,” said Zoox director of sensor engineering Ryan McMichaels.
Then there’s the fact that the robotaxi doesn’t care whether it’s coming or going, thanks to its symmetrical, bidirectional design. The advantages are tantalizing, particularly for a vehicle that’s going to be summoned on demand. There’s no more need for a three-point turn, and with its symmetrical steering axles, it should have unparalleled agility. For example, since both axles have the same degrees of steering, the Zoox robotaxi can crab walk far more effectively than the GM Hummer EV performing its party trick.
“Not only do we do that for the maneuverability, but also the redundancy of the vehicle,” said Stoffel. “The hardware inside of the vehicle, it’s the same rack, it’s the same EDU on both ends, same battery pack—kind of split in both ends—two HVAC units. There’s a lot of redundancy built in there. It kind of got the kitchen sink of redundancy as we wanted to make sure this first product really could complete the mission,” Stoffel told me.
“We’re picking people up and we’re dropping them off. How do we do that better than anyone else? The idea is to get into a spot that no one can or down a street or maneuverability that no one can, because we are really focused primarily on dense urban areas at the moment,” Stoffel said.

Zoox I haven’t had a chance to try out the rider experience yet, but I’m curious to see how it compares to the black cabs I grew up with in London. Those aren’t symmetrical, but they do have extremely tight turning radii, and an interior for riders that seats five with a pair of rear-facing jump seats—the best seat in the house for some.
Zoox’s interior is a little more stylish than the passenger compartment of a London taxi, though, with cup holders and wireless charging pads on both benches. “When you get into the vehicle… designing for calm is what we’ve wanted to go for. And the way we do that is nothing demands your attention. When you get into this thing, it’s very simple, it’s very clean, very continuous. Nothing is demanding your attention, allowing you to settle in. As simple as just doing your seatbelt and hitting go, you’re on your way,” Stoffel told me.
Zoox’s robotaxis are currently deployed in Las Vegas, San Francisco, and Austin, with Miami next in the works.
