Robotaxis are autonomous vehicles, or AVs, that provide ride-hailing services without the need of a human driver — and they’re quickly catching on as technology improves. Typically electric, these driverless cabs have the potential to ease traffic congestion, lower emissions and save money for passengers and companies alike, disrupting traditional taxi services and even the demand for personal cars in the long run.
Robotaxi Definition
Robotaxis are self-driving vehicles that provide on-demand transportation. Like traditional taxis, they can be hailed at-will through an app and shuttle passengers to their destination, but they do so autonomously — with no human driver behind the wheel.
With pilot programs already underway by industry leaders leaders like Waymo, Baidu and Zoox, self-driving taxis are expected to become a major player in future urban mobility, providing a more convenient and affordable way for people to get around.
What Is a Robotaxi?
A robotaxi is an autonomous, self-driving vehicle designed to pick up and drop off passengers on-demand. They are outfitted with a multitude of sensors, cameras, radar, LiDAR technology and audio receivers in order to navigate roadways, including traffic, obstacles and unpredictable behaviors known to urban streets.
Robotaxis are often associated with electric vehicle technology, as many of the models are either retrofitted EVs, hybrids or boxy new designs specifically designed for this purpose. They work similarly to ride-hailing services, like Uber and Lyft, but without the involvement of a human driver in the vehicle. Instead, passengers hail the vehicle using an app, and the robotaxi transports them to their destination — all while the onboard artificial intelligence controls the driving functions.
Robotaxi Examples
Waymo
Waymo, Google’s self-driving outfit under Alphabet, is a leader in the robotaxi space, becoming the first-ever company to offer driverless ride-hailing services to the public in 2020, as well as driverless rides on highways in 2025. The company’s all-electric fleet of modified Jaguar I-PACE electric SUV and Chrysler Pacifica Hybrid minivans have collectively driven upwards of 100 million miles without a driver, offering more than 10 million paid rides. Waymo operates in Phoenix, San Francisco, Los Angeles, Miami, Nashville, Orlando, San Antonio and Houston, plus Austin and Atlanta through partnerships with Uber.
Tesla
First announced in 2019, Tesla has been pursuing a robotaxi service for many years, slowly making gradual but significant progress. In 2024, the company unveiled the Cybercab — a purpose-built, fully autonomous vehicle that doesn’t even have a steering wheel or pedals — but it’s still pending regulatory clearance and the widespread rollout of unsupervised autonomous driving. For now, Tesla’s ridehailing services use Model 3s and Model Ys equipped with its Full Self-Driving software, and are limited to Austin, Dallas and Houston, plus Miami, Orlando and Tampa (with unsupervised vehicles), and the San Francisco Bay Area (with human safety drivers required by law).
Apollo Go
Multinational AI company Baidu operates Apollo Go, an autonomous ride-hailing service that uses LiDAR, cameras, radar and AI-based perception systems to navigate roads without a human driver. As of May 2026, Apollo Go had expanded to 27 cities worldwide and surpassed 22 million cumulative public rides, according to Baidu. The company is also pushing into international markets, with fully driverless operations underway in parts of Dubai and plans to test its robotaxis in London and Switzerland as it expands beyond China.
May Mobility
May Mobility is an autonomous vehicle company based in Ann Arbor, Michigan, specializing in on-demand autonomous transportation and microtransit. In Peachtree Corners, Georgia, the company operates a fully driverless public service using autonomous Toyota Sienna minivans, allowing riders to request trips between designated stops through its mobile app. May Mobility is also developing a next-generation autonomous ride-hailing platform as it works to scale driverless deployments beyond its current transit-focused services.
Pony.ai
Pony.ai operates commercial robotaxi services using vehicles equipped with LiDAR, radar, cameras and autonomous driving software to navigate roads without a human driver. The company has expanded beyond small pilot programs, with its robotaxi fleet surpassing 1,700 vehicles as of May 2026 and paid ride volume continuing to grow. Pony.ai is rolling out its latest-generation robotaxis across China while expanding internationally, and expects its fleet to exceed 3,500 vehicles by the end of 2026.
Zoox
Zoox, an Amazon subsidiary, operates a purpose-built, fully autonomous robotaxi without a steering wheel, pedals or driver’s seat. Its boxy, all-electric vehicles use cameras, LiDAR, radar and artificial intelligence to navigate roads while carrying passengers in a cabin designed specifically for autonomous ride-hailing. Zoox has opened its service to the public in Las Vegas and is offering rides to select members of the public in San Francisco, with additional testing and expansion underway in cities including Austin and Miami.
How Do Robotaxis Work?
Robotaxis utilize machine learning and artificial intelligence to navigate dynamic, unpredictable roadways. Generally, these vehicles are equipped with LiDAR, radar, 360-degree cameras and ultrasonic sensors that detect obstacles, map surroundings and track nearby objects, creating a unified picture so it can “see” its way around. This is known as “sensor fusion,” a process that enables autonomous vehicles to make real-time decisions in a matter of milliseconds, Steven Spieczny, vice president of marketing at AI-software company Kognic, explained.
“If you have a camera on top of the car taking a flat 2D image, while a radar scans ahead of the car’s position to determine a 3D perspective and an infrared LiDAR sensor on the side of the car, scanning for thermal activity — all these feeds need to be correlated and calibrated,” Spieczny told Built In. “These sensors record everything going on within proximity to the vehicle,” he continued. They’re asking “What are these ‘objects?’ What are they doing — are they stopped? Moving? How fast are they moving? What is the risk?”
The robotaxi’s built-in AI system processes this data, using machine learning algorithms to identify objects like pedestrians, other cars, traffic signals and obstacles in order to adjust the vehicle’s speed, direction and route accordingly — and all while reacting to traffic conditions, road hazards and passenger requests. Continuously learning, the system constantly collects information and updates its understanding of its environment in real time, enabling the vehicle to operate with minimal human input depending on its level of autonomy.
Levels of Autonomy in Robotaxis
Starting at zero, there are six different measures of autonomous driving standards. Reliance on a human driver reduces as you move up the ladder, with Level 5 representing a completely autonomous system. Here’s a quick rundown of each stage:
- Level 0 — No Automation: The vehicle has zero automation capabilities, and the driver is fully responsible for all aspects of control. Most “regular” cars fit in this category.
- Level 1 — Driver Assistance: This level includes basic driver assistance systems, such as adaptive cruise control or lane-keeping assist. But the driver is expected to remain attentive and engaged, overseeing the vehicle’s operation at all times.
- Level 2 — Partial Automation: The vehicle can autonomously control steering, acceleration and deceleration simultaneously under certain conditions, such as with Tesla’s Autopilot. However, the driver must be ready to take control if necessary, and their hands should remain on the wheel.
- Level 3 — Conditional Automation: The system can handle all driving tasks in most conditions, such as highway driving, but the driver must be available to intervene if needed. The car can handle tasks like speed control, lane management and obstacle avoidance, and will alert the driver to take over when it encounters a situation it can’t handle.
- Level 4 — High Automation: All driving tasks can be performed autonomously within certain geofenced areas or conditions. For the most part, a human driver is not needed to intervene — unless the vehicle travels into an unmapped area or finds itself in an extreme situation, like severe weather or unexpected obstacles on the road.
- Level 5 — Full Automation: The vehicle is capable of full autonomy in all conditions, without the need for a driver at any point. Its capabilities exceed human intervention, so much so that these vehicles are often built without a steering wheel or pedals. These vehicles can drive anywhere under any conditions without human oversight.
Safety and Testing of Robotaxis
Robotaxis undergo thousands of hours of testing over the span of a few years to a decade before they can take to the streets. This process involves simulations, closed-track tests and real-world testing under controlled conditions, all of which is supervised by safety drivers to ensure the vehicles are safe and reliable enough for public release.
But these systems are far from perfect.
Cruise, a former frontrunner in the self-driving taxi industry, was banned following a series of incidents, including one where a pedestrian was dragged several feet by a Cruise vehicle. These events led to regulatory investigations, caused Cruise to halt services in other areas and prompted the company to shift its focus away from developing its robotaxi fleet, according to its parent company General Motors.
And Cruise isn’t alone. Self-driving cars have been involved in several fatal accidents, including a 2018 incident where an Uber vehicle struck and killed a woman, partly due to the car’s perception system misclassifying her as an object rather than a person. Computer vision systems in general can struggle to see in the dark or around corners. They’ve also been known to malfunction in unpredictable ways, misinterpreting stop signs as 45 miles-per-hour speed limit signs or failing to recognize an articulated “slinky” bus, leading to collisions.
Even so, human error still accounts for about 94 percent of all traffic accidents, according to the National Highway Traffic Safety Administration. And the most recent data finds that autonomous vehicles are “generally safer” than human drivers “under certain conditions,” Spieczny noted. For example, a Waymo spokesperson told Built In that collision data from more than 33 million passenger miles shows Waymo vehicles 81 percent fewer crashes with airbag deployment and 78 percent fewer injury-causing crashes than an average human driver.
The challenge is that one “rare event” involving a driverless car can significantly hinder public perception of the technology. The only way to solve this is to capture more data and train these vehicles to handle these unique cases in the future. Waymo, for instance, is refining its driverless technology for winter conditions, testing it in upstate New York, Michigan and Northern California to expand its capabilities, according to the company spokesperson.
Vivek Joshi, an industrial automation engineer who has worked on product launches for robotaxis and other autopilot-enabled vehicles, likens the process to a baby first learning to walk before it can run.
“You still fall no matter how good of a runner you are — it’s more about how frequent the malfunctions are,” Joshi told Built In. “Companies constantly train their autonomous systems to be better by the day. It’s just a matter of time when we … gain enough autonomy to a point where almost every vehicle will be following a similar system, resulting in the lowest probability of accidents.”
Benefits of Robotaxis
Self-driving taxis pose a number of perks, for both riders and companies alike.
Reduce Human Error
Human error is responsible for the vast majority of car accidents. Equipped with smart sensors and advanced algorithms, robotaxis have the potential to enhance road safety, ridding roads of drunk, distracted, rage-filled or fatigued drivers who are making poor decisions at the wheel.
So far, autonomous vehicles can react in milliseconds — a rate that either matches or beats the average human, ranging from about 0.4 seconds to 1.5 seconds. But whether driverless cars are actually “safer” is too early to call. On average, an article from the National Law Review estimated that self-driving cars are involved in about nine accidents per million miles driven, compared to four accidents per million miles for traditional vehicles.
Relieve Traffic Congestion
Carpooling robotaxis could eventually become a daily norm for riders, reducing the reliance on personal car ownership. This would put fewer cars on the road while allowing smart AVs to improve road efficiency — potentially up by 35 percent, a 2019 University of Cambridge study found — as they coordinate with one another, adjusting speeds to prevent stop-and-go patterns and avoid bottlenecks.
Also, consider that driverless taxis do not need to park near destinations, which would free up parking spaces and reduce blockages caused by parking — an inevitable nuisance that accounts for 30 percent of city congestion, according to the U.S. Department of Transportation.
Reduce Carbon Emissions
Robotaxis — especially electrically-powered models — offer many eco-friendly features, such as optimizing routes, minimizing idle time, promoting carpooling and the elimination of energy-sucking driving patterns, like excessive acceleration or braking.
Cut Costs
Driverless robotaxis can cut costs by eliminating the need for human drivers — one of the biggest expenses in ride-hailing. Research from McKinsey shows that autonomous vehicles could halve operational costs by 2030, meaning cheaper rides for passengers and higher profits for companies. And, by 2035, the industry as a whole could create $300 billion to $400 billion in revenue.
Challenges of Robotaxis
Even with impressive tech innovations and safeguards in place, robotaxis still need to navigate several off-road obstacles.
Safety Concerns
Autonomous vehicles are widely considered to be safer than having a human behind the wheel, but it’s a bit more complicated than that.
While Waymo and the now-defunct Cruise claim their vehicles are safer than human-driven cars, their reported crash rates raise questions. Waymo reported 4.5 crashes per million miles in 2023, compared to the national average of 1.94. Additionally, Cruise reported a higher crash injury rate of 1.0 per million miles at its Phoenix-based operations, which is above the average injury crash rate for drivers in that area. Keep in mind that these pilot programs are also skewed, as they are restricted to limited areas with favorable conditions.
Public Perception
People are still hesitant to jump in a self-driving car. In a 2025 survey by AAA, only 13 percent of U.S. drivers would trust to ride in a self-driving vehicle. Though it is nine percent higher than what was reported in 2024, it pales in comparison to India and China, where over 50 percent of drivers trust self-driving cars. While the U.S. may see early adopters, robotaxi companies may find it harder to reach mass adoption.
Regulatory Requirements
Laws that dictate what autonomous vehicles can and can’t do vary widely by region. In California, for example, companies must obtain the proper permits and licenses, report collisions in a certain way and ensure a safety driver is present in every test vehicle, regardless of its level of autonomy. In contrast, states like Arizona — incidentally, where the first robotaxi-related death occurred — are a bit more lax when it comes to regulations.
This lack of standardization will ultimately delay the widespread adoption of autonomous vehicles, stalling even the most successful AV companies as they scale.
The Future for Robotaxis
When it comes to the mainstream adoption of robotaxis, it’s no longer a question of if, but when. As technology advances and regulations catch up, they are poised to become a fixture of everyday life
Now that these AV companies are clocking hundreds of paid trips by the week, “the growth will continue,” Spieczny said. The market is already projected to multiply from its $3.3 billion valuation to $50 billion by 2032. “Once people see for themselves that autonomous vehicles are safe and affordable, they’ll be much more open to hopping in a robotaxi,” he predicted.
Once they are fully integrated into society, robotaxis are expected to transform urban transportation, reducing congestion and providing a more efficient way for commuters to get around. With fleets of self-driving cars zipping through cities, passengers could request rides on demand through an app, eliminating the need for car ownership altogether. And as cities become more automated, these vehicles could seamlessly connect with other smart infrastructure, like traffic lights and public transportation, creating a more cohesive mobility system.
“Everything that moves — at some point in the future — will require autonomous systems,” Spieczny continued. “Cars and trucks are just the beginning of that overall embodied AI future.”
