I'm going with Firetrux on this.
I thought I would hate most of the eyesight features, and really only cared about blind spot detection (super helpful at night), and rear cross-traffic detection. But they have proven their worth.
I like the active lane keeping and leave it on all the time. It requires you to turn it on, and it remembers the state in which it was in when you turned the vehicle off. If it activates, you can steer out of it. You do have to remember to signal lane changes to avoid getting beeped at, and that's a good thing.
As for the lane departure warning, you can disable that for the driving session, but defaults to on when the engine restarts. It's pretty accurate. The biggest problem it has is when two lanes merge into one without a line between them. It always warns then. It also dongs if it can't see any right or left line, and it shows you which line(s) it is seeing.
The lane sway warning is intended to tell you when you're tired and drifting in the lane repeatedly. It only works when the lane departure warning is on. I've never had it warn me, so I don't believe it's very sensitive.
The active cruise control does reasonably well in heavy traffic. My biggest problem is that when it slows down for a slower driver ahead, I sometimes don't notice that (despite notification on the dash) and go slower than I intend until I do notice and pull out to pass. But if you don't like active cruise control, you can make the vehicle use the traditional mode by the way you activate it when you turn it on.
As for the pre-collision braking system and throttle management, as Firetrux said, you can turn them off for the session. I keep them on. I've had them activate a couple of times. One time I stopped, the other time I steered out and accelerated.
I've gone from a skeptic to a believer. I wouldn't buy another vehicle without those features, though I'd pass on any vehicle whose manufacturer required you to get the absolute top end vehicle to get them. Honda, for example, gives you those systems at mid-range, but requires you to spend much more money to get blind spot and rear cross traffic, and that's just stupid!
