Autonomous driving systems are technologies that enable vehicles to navigate and operate without human intervention. These systems use a combination of sensors, cameras, and artificial intelligence to perceive their surroundings, make decisions, and control the vehicle's movements. The goal is to enhance safety, reduce traffic congestion, and improve transportation efficiency. These systems are often categorized into different levels of automation, ranging from Level 0 (no automation) to Level 5 (full automation). Companies like Waymo and Tesla are at the forefront of developing these technologies, which have the potential to transform the future of transportation.
