The future of transportation is moving toward autonomous or self-driving technology. These systems use a combination of cameras, LiDAR, and radar sensors to perceive the environment around the car. Artificial intelligence algorithms process this data in real-time to make decisions about steering, braking, and navigation. Companies like Waymo and Tesla are at the forefront of developing software that can handle complex urban traffic without human intervention. There are different levels of autonomy, ranging from simple cruise control to fully driverless systems where no steering wheel is needed. While autonomous cars promise to reduce accidents caused by human error, there are still many legal and ethical questions to be answered. Ensuring the security of these connected systems is critical to prevent hackers from taking control of the vehicle remotely.
