Driverless vehicles are no longer a futuristic concept. With the incredible advancement of advanced driver assistance systems (ADAS), autonomous vehicles are very much part of the present moment.
Autonomous vehicles rely on radars and sensors to maintain safe and efficient driverless 'driving', including driver assistance technologies such as collision warning systems, automatic emergency braking, and lane departure warnings.
