Since you mention it, John -
Since you mention it, John - the Eyesight that is available on the Subaru Forester is still Gen 1, and basically adds about $800 to the cost of the car. (The All Weather Package on a Premium Forester adds $500 to the MSRP - the bundle of AWP plus Eyesight adds $1295.) The Eyesight on the 2015 Legacy and Outback is Gen 2, and on the Premium Legacy is available in a bundle with Blind Spot Detection and Rear Cross Traffic Alert for $1295. (The Outback adds $1695, because it also adds in the power rear lift gate.)
So we're talking $26,362 MSRP for a nicely equipped 2015 Premium (cloth seats) Legacy - WITH Eyesight. I realize that Eyesight may not have prevented the collision - but as the IIHS points out, it should reduce the collision from, say, a 40 mph crash to a 15 mph crash - and guess what? It MIGHT have prevented this crash.
