2017 Legacy with "Eye Sight." I have had one or two situations where the car emergency braked on my behalf. It happens when the car in front of me turns off the road and is nearly clear. I don't brake because I know that the car will clear the roadway before I get there but the system doesn't see it that way and brakes. I anticipate that now and avoid anything close enough to cause braking so I don't wind up the front end of a rear end collision. The other thing this system does is to provide adaptive cruise control. If I'm behind a vehicle that results in slowing down and then switch lanes (to where there is another vehicle in front of me) the car seems to think it can resume speed and slip between the two vehicles. I've come to expect that too and disengage the speed control before switching lanes. It also provides a warning when approaching the lane markings (unless I have indicated a lane change.) Occasionally it triggers on seams in the pavement. It also provides steering input if the land deviation increases. I've only experienced when I tested it in purpose. I'm not sure it would reliably keep the vehicle in the lane. Overall the system seems to be pretty good and though not perfect, is a net asset.
