Greg Brannon, director of automotive research at AAA, details the results of a new technical evaluation of traffic-jam driver-assistance technology. Researchers found it experiences a “notable event” every 9.1 minutes.

He examines the differences in performance between hands-off and hands-on traffic-jam assist technology and offers automakers solutions for improving future systems. 

Further, Brannon looks at how even well-performing systems can lull drivers into a state of automation complacency, which brings its own set of problems, and he discusses the gap between automotive marketing promises and the real-world reality of driver-assistance performance and limitations.
