Tesla Autopilot is an advanced driver-assistance system designed to enhance vehicle safety and convenience. It uses a combination of cameras, radar, and ultrasonic sensors to monitor the car's surroundings, allowing it to perform tasks like steering, accelerating, and braking automatically under certain conditions. While Tesla Autopilot can assist with driving, it is not fully autonomous. Drivers must remain attentive and ready to take control at any time. The system is continually updated through software improvements, making it more capable over time while ensuring compliance with safety regulations.
