What Is Waymo? Cars, Technology and How It Works
What is Waymo? Waymo is Alphabet's autonomous ride-hailing company and the operator of a commercial SAE Level 4 robotaxi service. Its Waymo Driver combines lidar, cameras, radar, onboard computing and detailed maps so the vehicle can complete a trip without a human driver inside its approved service area. The fleet uses electric Jaguar I-PACE vehicles and is introducing the purpose-built Ojai with Waymo's sixth-generation system.
What is a Waymo car?
Waymo is Alphabet's self-driving car company and operates one of the world's largest commercial robotaxi services where trips run with nobody in the driver's seat. Its cars are Level 4 autonomous inside their mapped service areas, and its current rider fleet is built mainly on the electric Jaguar I-PACE. That is fundamentally different from Level 2 consumer systems, which still require a human driver to supervise the road.
This article answers the questions people actually ask about Waymo: what the company is, how its self-driving cars work, what cars it uses, where you can ride one, how safe it is, and how it stacks up against Tesla.
Waymo is no longer a test project. By July 2026 its driverless cars carry paying passengers across multiple US cities, with more service areas opening in stages. Current rider vehicles are electric Jaguar I-PACE SUVs, while the purpose-built Ojai is joining the fleet and Hyundai IONIQ 5 vehicles are being validated. Availability changes faster than a static article can track, so Waymo's live rides page is the final check for a specific city.
Where Waymo came from
Waymo is an Alphabet company, under the same parent as Google. It started as Google's self-driving car project in 2009 and became a standalone Alphabet company in 2016. That long development history matters, but time alone is not the advantage. Waymo built a loop that connects simulation, closed-course testing, public-road data, fleet operations and a defined safety-readiness process. The operating system around the vehicle is as important as the years on the calendar.
What cars does Waymo use?
For several years the face of the fleet has been the Jaguar I-PACE, an all-electric SUV carrying Waymo's fifth-generation Driver. It replaced the Chrysler Pacifica minivans that Waymo retired from its all-electric ride-hail fleet. The next vehicle is Ojai, a purpose-built electric ride-hail platform with sliding doors, a flat floor and Waymo's sixth-generation Driver. Waymo began inviting selected public riders into Ojai in 2026. A Hyundai IONIQ 5 platform is also in validation. Vehicle introduction and public availability are separate milestones, so a validated platform should not be counted as a customer fleet until Waymo opens it to riders.
What Key Features Set Waymo Apart?
| Feature | Description |
|---|---|
| Level 4 autonomy | Waymo runs at Level 4, which means the car drives itself with no human intervention inside its mapped service area. That is a step beyond Tesla's Level 2 Full Self-Driving (FSD), where the driver must stay ready to take over. Waymo handling dense city traffic with an empty driver's seat is the clearest proof of the gap. |
| Lidar and sensor suite | Each Waymo carries lidar, cameras and radar working together. Lidar builds a detailed 3D map of everything around the car, which lets it place pedestrians, cyclists and other vehicles precisely, and keeps working at night or in glare, where cameras alone struggle. |
| Real-world miles | Waymo's Safety Impact dashboard covered 220.6 million rider-only miles through March 2026 across Phoenix, San Francisco, Los Angeles, Austin and Atlanta. That is operational evidence inside Waymo's specific service areas, not proof that the system can drive everywhere. |
| The cars and how you book them | The established rider fleet uses the all-electric Jaguar I-PACE, while Ojai is entering selected public service. You hail through the Waymo app in direct markets or through Uber in partner-operated markets such as Austin and Atlanta. |
| Safety record | Waymo's June 2026 analysis reported 94% fewer serious-injury-or-worse crashes than a human benchmark over the same distance in its operating cities. The comparison includes every reported Waymo collision regardless of fault, but it remains a matched-area rate comparison, not a claim about every road or weather condition. |
How does Waymo work?
From the passenger's side it is simple: you open an app, request a ride, and an empty Jaguar I-PACE pulls up and takes you there. Underneath, the car combines its lidar, camera and radar feeds into a live 3D model of the street, then matches that against a high-definition map Waymo has already built of the area. It plans a path, predicts what other road users will do, and drives, no remote pilot steering it. Human operators sit in the background and can give the car guidance if it gets stuck, but they do not drive it.
Does a person remotely drive a Waymo?
No. Remote assistance is advice, not teleoperation. When a vehicle meets an unusual blockage or ambiguous scene, it can request help and send context to a fleet-response agent. The agent may clarify the situation or suggest a path constraint, but the onboard Waymo Driver still evaluates the road and commands steering, braking and acceleration. If the advice is unsafe or stale by the time it arrives, the vehicle can reject it.
This design matters for both latency and scale. A remote joystick driver would need a continuous, low-delay connection and would inherit the complete driving task. Advice can arrive less frequently because the car remains responsible for immediate motion and collision avoidance. The human layer still matters operationally, but it does not turn a Level 4 vehicle into a remotely driven taxi.
Booking depends on the city. In San Francisco, Los Angeles and Phoenix you use the Waymo One app directly. In Austin and Atlanta the rides come through the Uber app instead: Waymo and Uber run those markets together, with Uber handling dispatch and Waymo running the cars. Cruise, the GM-backed rival that once looked like Waymo's closest competitor, was wound down after GM pulled its funding in late 2024.
Waymo vs Tesla: who leads in self-driving?
This is the comparison everyone wants: is Waymo better than Tesla? The honest answer is that they are not yet doing the same thing. Tesla's Full Self-Driving (FSD) is a Level 2 system: impressive, available on cars you can buy, but it still needs a human ready to take over at any moment. Waymo's cars are Level 4 and carry paying passengers with nobody in the front seat. On the core measure (can it drive with no human in the loop?) Waymo is ahead today.
The two also make different system choices. Waymo uses lidar, radar, cameras and a detailed mapped operating area, then expands service city by city. Tesla's consumer system relies mainly on cameras and a broad fleet footprint, without Waymo's lidar suite or tightly mapped robotaxi domain. Tesla has the larger hardware population. Waymo has far more public rider-only operation. Cost, scalability and driverless capability must be compared separately, which is why neither installed-vehicle count nor autonomous miles settles the whole argument. We lay out the complete picture in our Tesla Robotaxi vs Waymo comparison.
Does Uber offer self-driving rides?
Yes, in some cities, through Waymo. In Austin and Atlanta, requesting a standard Uber can match you with a driverless Waymo instead of a human driver, and you can set whether you want that in the app. Uber itself does not build self-driving cars; it offers them through partners. For a while that included GM's Cruise, but Cruise has shut down, so Waymo is the partner that matters now.
What happened to Cruise?
Cruise, owned by General Motors, was for years seen as Waymo's closest rival and ran its own driverless taxis in San Francisco. That changed after an October 2023 crash in which one of its cars dragged a pedestrian; Cruise lost its California permits and grounded the fleet. In December 2024 GM stopped funding the robotaxi business and folded what was left into its own driver-assistance work. The upshot for riders: among large, genuinely driverless services in the US, Waymo is now effectively on its own, with Tesla still working toward a comparable public service.
EV-Global verdict: where self-driving goes next
Waymo has settled the question of whether a paid, fully driverless taxi can work on real city streets. By May 2026 it had served more than 20 million fully autonomous rides. The open questions are money and reach: whether the lidar-and-mapping approach can expand cheaply enough to cover whole metros, and how competing systems will perform at comparable scale. The technology has moved from demo to daily transport.
How Waymo fits into the autonomous-car stack
Waymo is the clearest production example of SAE Level 4 automation. The responsibility boundary becomes easier to see in our Level 2 vs Level 3 comparison. For the competing approaches, see Tesla Robotaxi vs Waymo, how AI drives an autonomous car, and the computing layers behind it in Nvidia Automotive, the software-defined vehicle and zonal E/E architecture.
