Here’s something most people don’t know about robotaxis. Until now, Waymo’s driverless cars started life as regular cars. Waymo bought them, then fitted its own sensors and computers afterward at its plant in Arizona.
That’s about to change. On October 30, Toyota and Waymo announced a Toyota bZ4X robotaxi that’ll get Waymo’s self-driving gear right on the factory line in Japan. It sounds like a small manufacturing detail. Honestly, though, it’s one of the more important robot stories of the week, because it’s about building self-driving cars the same way regular cars come off a line.
So what did Toyota and Waymo actually announce?
Toyota will build the 2027 bZ4X, an electric SUV sold as the bZ in North America, at its Takaoka plant in Toyota City, Japan. During that same assembly run, it’ll install Waymo’s sensors and computers. So the robotaxi versions roll off the same line as the regular ones.
Testing starts in Japan in 2027, according to TechCrunch. The plan targets right-hand-drive countries first, including the UK. Waymo’s co-CEO, Dmitri Dolgov, confirmed the order. “We’ll start with the right-hand drive markets in Japan and the UK,” Dolgov said.
The two companies first agreed to explore working together in April 2025. TechCrunch described that early deal as pretty vague. Now there’s an actual car attached to it.
“This collaboration will help scale that technology and bring it to customers in Japan and beyond,” said Toyota’s Hiroki Nakajima. Both sides will also keep exploring Waymo’s tech for personally owned Toyota cars, so this might not stay a taxi-only story forever.
Why a factory-built Toyota bZ4X robotaxi matters
Think about the old way for a second. Every Jaguar or Zeekr that Waymo adds to its fleet needs a separate trip through its Arizona plant, according to The Next Web. That works, but it’s an extra step for every single car.
Putting the hardware in at the factory changes the math. In theory, it means fewer handoffs, more consistent builds and an easier path to scale. We don’t have Toyota’s numbers to prove that yet, so take it as our read, not a promise.
Riders get a few perks too. The bZ4X robotaxi comes with automatic doors and a power tailgate. That matters more than you’d think when nobody’s in the driver’s seat to help with your bags.
There’s also the Toyota factor. The carmaker has been busy in robotics lately, including its big humanoid robot plan. Meanwhile, Waymo has been growing fast at home, as we covered in our look at its robotaxi fleet plans. Pairing Toyota’s factories with Waymo’s driving system is a serious combo.
Japan first, then London
Japan makes sense as the starting point. It’s Toyota’s home turf, and Waymo already tests in Tokyo with safety drivers, according to The Next Web. Competition is heating up there too, since Uber, Wayve and Nissan plan their own robotaxi pilot in Tokyo.
London is the other big target. Waymo has tested Jaguar I-Pace cars there for months, and it plans to launch a service once it gets the necessary permits. We’ve written about how crowded that race is getting, with Uber bringing in Pony.ai.
Still, don’t book your first driverless ride in Tokyo just yet. The companies call 2027 a testing and validation phase, not a commercial launch. And the bZ4X has no UK timetable at all.
Why right-hand drive first? Japan and the UK both drive on the left, so cars there have the steering wheel on the right. Motor1 calls this Waymo’s first factory-integrated program for right-hand-traffic markets.
What we still don’t know about the Toyota bZ4X robotaxi
Quite a lot, actually. Neither company has said how many cars Toyota will build. There are no financial terms, and no dates for paid rides in Japan or the UK.
Dolgov was pretty direct about it. “We don’t have any other countries or timelines or specifics to share,” he said. According to Motor1, Toyota’s chief technology officer also said the first fleet will stay small.
That’s fine by us. Big carmakers move carefully, and London alone still needs permits before any service starts. We’d rather see a slow rollout that works than a splashy one that stalls.
There’s also the question of how fast this could scale if testing goes well. Takaoka already builds the regular bZ4X, so in theory the line is there. But a factory line isn’t the same as demand, permits or a business case, and none of those are settled yet.
Okay, but why should you care?
If you live in Yerevan, a Toyota bZ4X robotaxi isn’t pulling up outside your door any time soon. But this deal matters well beyond Japan and London.
It shows physical AI (AI that acts in the real world instead of only on a screen) moving from custom conversions toward regular factory production. Once robotaxis roll off the same lines as normal cars, they could get cheaper and easier to bring to new cities. That’s how a technology goes from a novelty in a few rich cities to something emerging markets might actually see.
For startups and engineers, there’s a lesson here too. In physical AI, the software gets the headlines, yet the boring stuff often decides who wins: manufacturing, permits, safety testing and partners who can build at scale.
So here’s our question for you. When carmakers build robotaxis like any other car, what’s the first thing that’ll change about how your city moves?
