I bought my new 2013 Outback in 2012. The '13 was the first Outback with Eyesight. I looked at all the Eyesight info the salesman had and most of it seemed to be fine print explaining when and why it wouldn't work. So I skipped it. Moot point anyway because I found that an Outback couldn't have both Eyesight and a stick shift, and stick shift was my main priority.
I've just been looking at the 2022 version of the Eyesight manual, 176 pages and jam packed with disclaimers, but also a lot of reasons why Eyesight might not work, including modified headlights or foglights, misfiring middle windshield squirter that cleans the camera, bad tire pressures, loaded/tilted car, trailer towing, non-OEM parts, rain drops on windshield, Rain-X or similar, following a flat-bed trailer, up or down steep hills, worn wiper blades etc.
Pages 30-36 list the myriad of reasons that the pre-collision braking system might not work.
140 pages to go.
I wonder how many drivers read every page of every manual.
