An autonomous vehicle is a type of transportation that can drive itself without human intervention. These vehicles use a combination of sensors, cameras, and artificial intelligence to navigate roads, avoid obstacles, and follow traffic rules. They aim to improve safety and efficiency in transportation. The technology behind autonomous vehicles includes systems like LiDAR, radar, and computer vision. Companies such as Waymo and Tesla are leading the development of these vehicles, which have the potential to reduce accidents caused by human error and provide mobility solutions for those unable to drive.
