Self-driving cars are autonomous vehicles equipped with a combination of sensors, cameras, and AI algorithms that allow them to navigate without human intervention. They operate using a mix of real-time data from the environment, including road conditions, obstacles, and traffic signals, processed by advanced machine learning models. These vehicles utilize a complex decision-making framework to understand and react to their surroundings, aiming to ensure safety and efficiency. Ultimately, self-driving cars have the potential to reduce accidents, enhance traffic flow, and redefine personal transportation through innovative technologies.
