In recent years, self-driving technologies have evolved from futuristic concepts to practical tools that ordinary drivers can use every day. Although fully autonomous vehicles (Level 5) remain the ultimate goal, many cars on the road today incorporate advanced driver-assistance systems (ADAS) that offer semi-autonomous features. These systems, including adaptive cruise control, lane-keeping assist, automated emergency braking, and even hands-free driving on highways under certain conditions, are changing the way drivers interact with their vehicles. In this article, we explore how an ordinary driver uses self-driving technologies, the benefits they offer, real-world applications, and the challenges that still need to be addressed.
