Self-Driving CarsSelf-driving cars are autonomous automobiles that can operate without human intervention. This includes safely navigating from one destination to another while adhering to traffic rules and responding to changing road conditions without a human taking over.
These machines rely on a suite of sensors—including radar, lidar (which uses lasers), and photographic technologies—to perceive the world around the vehicle. Data collected by these sensors is used to create a “map” of the environment to identify everything from street signs and traffic signals to other vehicles and pedestrians. That map is constantly updated, allowing an artificial intelligence program to make decisions about when to accelerate, brake, or turn in order to travel safely.
As of the fourth quarter of 2025, no fully autonomous self-driving cars are available on the market for consumers. However, some companies, such as Waymo and Mercedes-Benz, are testing self-driving vehicles on public roads.Explore Self-Driving Cars
What we've found
As of 2025, self-driving cars continue to be unavailable to consumersThese vehicles rely on radar, cameras, lidar, and advanced AI to process data and make real-time driving decisions. Companies like Waymo and Mercedes-Benz are testing autonomous cars on public roads, but challenges remain, including technical reliability issues, regulatory hurdles, and a lack of consumer trust. 1440Explore 14 iconic self-driving cars from television and filmFrom the heroic KITT from "Knight Rider" and Batmobile from "Batman" to the demonically possessed Christine from Stephen King’s "Christine," many of the vehicles on this list are examples of how classic cars have been personified in media. Top GearIn a 2024 survey, 93% of participants expressed concerns about self-driving carsSafety was the leading consumer fear, with technological malfunctions coming in second. Nearly half of all consumers identified skepticism or concern as their primary descriptor for autonomous cars, but 20% cited enhanced mobility for the elderly and people with disabilities as a key benefit. ForbesIn 2023, self-driving cars drove 3.3 million miles on California's roadsAccording to the state's DMV, the mileage represented a fivefold increase from the previous year. General Motors' Cruise and Alphabet's Waymo accounted for the bulk of miles, though 38 companies have received permits to test autonomous vehicles in the state. ReutersFuture self-driving cars may communicate across a closed wireless infrastructureCurrent autonomous vehicles collect and analyze their own data through their own hardware and proprietary software. Connecting data from all such cars on a single network will require overcoming challenges related to standardization and security. Bloomberg TechnologyGoogle invented the foundation of the AI movement—but ChatGPT was a shockFor years, Google was the cutting-edge of the AI world, including the development of the Transformer—the basis of contemporary AI chatbots. But since OpenAI debuted ChatGPT in 2022, the company was had to play catch-up. This is a four-hour deep dive into Google's AI history. AcquiredSelf-driving car companies like Waymo use lidar technology for navigationBy firing thousands of laser pulses in all directions, lidar systems construct 3D maps of a car’s surroundings, even in environments with limited lighting. The technology has also been incorporated into iPhones and the Vision Pro headset to improve camera focus. The VergeAutonomous vehicles have been confirmed to reduce greenhouse gas emissionsResearch indicates that self-driving cars can reduce harmful pollution through lower traffic, decreased parking demand, and optimized driving behavior. These benefits can be enhanced further in smart cities with responsive traffic signals. AZoCleantechSelf-driving formula cars race in the Abu Dhabi Autonomous Racing LeagueThe league and high-speed versions of traditional cars help to showcase the capabilities of driverless vehicles and the reliability of their AI systems. Leonardo da Vinci first imagined the idea for such machines in the 16th century. Interesting EngineeringExplore the components of autonomous vehicles controlsA suite of cutting-edge hardware and computation-intensive software creates the potential for self-driving cars to be safer, more fuel-efficient, and more accessible to a broader range of drivers. However, automation also introduces potential cybersecurity threats. DORLECOExplore the National Highway Traffic Safety Administration's guide to automated carsThis page provides answers to questions on topics ranging from liability for crashes involving autonomous cars to the safety benefits of these cars. A timeline of the evolution of automated safety technologies is also provided. National Highway Traffic Safety AdministrationThe Society of Automotive Engineers sorts self-driving technology into six levelsAt level 0, a vehicle cannot intervene on its own, and the driver controls all navigation. At level 3, the car operates autonomously under limited conditions, but a human can still take control. A future level 5 vehicle drives itself and lacks a steering wheel or pedals. Kelley Blue BookView a list of companies owned by Google's parent company, AlphabetThese companies include Google subsidiaries like YouTube, the biggest online video sharing and streaming platform, Nest, which manufactures smart products like speakers and thermostats, and Waymo, the technology company developing self-driving cars. Industry Leaders MagazineMachine learning lets computers learn from data instead of relying on programmingML is a core part of artificial intelligence and is foundational to applications like chatbots, fraud detection, and self-driving cars. Businesses are also adopting it to improve efficiency and identify patterns in data, though the latter may be inaccurate. MIT
