In recent years, a number of car companies have—like Tesla—begun offering driver assistance systems that offer lane-keeping as well as adaptive cruise control. This might seem like a big step toward a “self-driving car,” since a system like this can travel down the freeway for miles without human intervention. But a new report from AAA underscores the limitations of these systems.
Its most dramatic finding: the advanced driver-assistance systems (ADAS) on the latest cars still struggle to avoid collisions with parked vehicles. They tested cars from BMW, Kia, and Subaru; none consistently avoided running into a fake car partially blocking the travel lane.
The researchers also examined the ADAS in the Cadillac CT6 and the Ford Edge, but these cars’ systems weren’t included in the parked-vehicle test because their driver assistance systems wouldn’t engage on AAA’s closed course. They were included in other tests conducted on public highways.
