Hours of research by our editors, distilled into minutes of clarity.
By 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.
These 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.
At 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.
Research 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.

According 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.
The 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.
A Tesla Model X collided with stopped emergency vehicles on a Texas highway when flashing lights created hazy images that the software could not interpret. The crash injured five people and hospitalized another person while highlighting the challenges of autonomous systems.
About 70% of Americans feel uncomfortable riding in a driverless car, and 81% of them would not fly on a pilotless plane. However, automated systems on planes were slowly introduced and advertised as enhancing safety—an approach that may benefit driverless vehicles.
Honda's "Riding Assist Technology" was introduced in 2017 and maintains the motorcycle's stability by leaning away from the direction of the front wheel and adjusting the front fork's angle at low speeds. Yamaha's system uses actuators to achieve balance during stops and starts.
A 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.
Since the time our ancient human relatives began using stone tools to perform tasks, humans have harnessed scientific knowledge and new technologies to advance our ability to feed ourselves, increase our health, expand the boundaries of our knowledge, and much more. From artificial intelligence and quantum computing, to optimizing the human body in pursuit of a long and healthy life, and much more—learn about these topics and more with our smart-but-digestible overviews and expert-curated resources.
