2013/14 2.5i-L CVT
The Eyesight manual warns that ACC not be used in urban areas as it can be slow to react in complex situations. It can take 2-3 seconds to respond to new objects which means the car will have travelled 64-96 feet at 35 mph before Eyesight even begins to react.I have a 2016 Forester with Eyesight and use the Adaptive Cruise Control everyday on my commute to work as well as driving down local roads.
Bottom line: Eyesight isn't designed to be the driver. That is our job. It is merely an aid to, hopefully, catch when we make a mistake and to ease the workload on long distant highway trips.
