A new study finds that drivers using driver assistance features often treat their vehicles as fully self-driving.

“These applications still require the human to keep their eyes on the road and hands ready to take over the wheel, just as we have been doing with traditional cruise control for decades,” Stan Caldwell, a professor of transportation and public policy at Carnegie Mellon University told Lifewire in an email interview…

Vehicles that you can buy currently can have levels 1 and 2 automation and include applications such as automated lane keeping, adaptive cruise control, and automated emergency braking, Caldwell said.

“Level 3 automation is coming, and already on some roads in Germany with Mercedes, where eyes can be off the road, but the human driver still may have to take over,” he added. “My concern is that if people are already over-relying on Level 2 automation, the situation may get worse.”
