A self-driving car, also known as an autonomous vehicle, is a type of vehicle that can navigate and operate without human intervention. It uses a combination of sensors, cameras, and artificial intelligence to understand its surroundings and make driving decisions. This technology aims to improve road safety and reduce traffic congestion. Self-driving cars are designed to follow traffic rules, avoid obstacles, and communicate with other vehicles. Companies like Waymo and Tesla are leading the development of this technology, which has the potential to transform transportation by providing greater accessibility and efficiency for all users.
