Autonomous vehicles are powered by a combination of sensors, machine learning, and artificial intelligence (AI). Sensors like LIDAR, cameras, and radar provide real-time data about the vehicle's surroundings, allowing it to perceive obstacles, traffic signals, and other vehicles. Machine learning algorithms enable the car to learn from experiences and improve its driving performance over time. Furthermore, the integration of AI handles complex decision-making processes, such as route planning and navigation, making autonomous vehicles capable of operating safely in diverse environments.
