Self-driving cars, also known as autonomous vehicles, operate using a complex system of sensors, cameras, and artificial intelligence algorithms. These vehicles are equipped with Lidar sensors, which use laser beams to create a 3D map of the surrounding environment. They also have cameras that detect lane markings, traffic lights, and other vehicles on the road. The artificial intelligence algorithms process this information in real-time to make decisions on when to accelerate, brake, and change lanes. This technology allows self-driving cars to navigate through traffic, adapt to changing road conditions, and avoid collisions. In addition, self-driving cars are constantly learning and improving their driving abilities through machine learning. This means that the more they drive, the better they become at predicting and reacting to different scenarios on the road. Overall, self-driving cars are revolutionizing the way we think about transportation by offering a safer, more efficient, and convenient way to travel. As this technology continues to advance, we can expect to see more autonomous vehicles on the roads in the near future.
