The ADAS Landscape: How Did We Get Here?

The Evolution of Driver Assistance

Remarkably, some forms of driver assistance date back to the late ‘90s, primarily in luxury models. Originally conceived as basic adaptive cruise control and trajectory warning systems, ADAS now integrate hundreds of sensors, high-definition cameras, radar, lidar, and AI. According to the Insurance Institute for Highway Safety (IIHS), ADAS features have already contributed to a measurable reduction—up to 27%—in certain types of accidents such as rear-end collisions.

Today’s landscape is defined by a “racing arms” scenario, where brands each cultivate proprietary technologies and partner with software giants. From hands-on warning systems to near-autonomous cruising, consumers have a dazzling range of capability to choose from. Understanding these differences is pivotal.

Defining Levels of Assistance

Driver assistance systems are generally categorized using the SAE International levels:

• Level 1: Basic driver assistance (lane keeping OR adaptive cruise)
• Level 2: Multiple partially automated functions, but full driver supervision (e.g., Tesla Autopilot, GM Super Cruise)
• Levels 3 & 4: Some unsupervised features under limited conditions (e.g., Mercedes Drive Pilot in select roads)
• Level 5: Fully autonomous driving (not yet available commercially)
