Anyone else experience this? When a car moves into your lane ahead, eyesight does not pick it up until it's fully in the lane, and will not slow down to let them in. Meanwhile it will allow the car to get dangerously close- for example when you're in a fast moving lane and the other car enters from a slower lane. Seems like a major error? The cameras should be able to see this unfolding.

I've found that moving within your lane toward the side that vehicles are entering from and away from vehicles leaving your lane helps Eyesight keep up with these dynamic situations better.

Eyesight has to process a lot of stuff within it's limited field of view and it doesn't have the benefit of peripheral vision like we do.

I'm always ready to take over especially in heavy traffic because I can see things Eyesight can't.

Yes. I learned that early on and I think I mentioned that in an earlier post. I definitely remain alert and poised to take control as needed.

Yea I'm alert, but it seems line the kind of thing that is actually in the field of view. The merging car would literally be on a collision course straight ahead. Maybe moving over a bit would help the system "see" it. But it's not great having such random "exceptions"for what eyesight can react to. Doesn't instill a ton of confidence. Also not slowing down isnt really an option, that's the point. We're talking about when cars switch into your lane and not yet up to your speed...

Totally agree and I'm not making excuses for it. It could certainly be better. It seems it's locked on the car in front and doesn't recognize there's a merging vehicle until it's quite far in the lane. Moving toward the merging vehicle will force this to occur sooner than otherwise, but either way, hitting the brakes or moving over, it remains on the driver to take action in a situation where you think the system should work.

My wife was driving and hates the green light and associated beep. With me in the passenger seat I was able to verbally add another beep at nearly the exact time it came in. It always seems to be when the merging vehicle is about halfway in my lane. She hates that lol
Depending on the gap I agree with @GaryInMI on moving slightly toward the merging vehicle to help eyesight recognize itmore quickly

FYI both the beep and the green HUD can be disabled in your Combination Meter Settings.

I silenced the beep but keep the green light.

I drive in heavy SF Bay Area traffic where last minute lane changing with zero spacing is a way of life. The Eyesight utterly fails to see the car that is cutting in front of you until it is FULLY in front of you, at which point in heavy traffic, you have to jam on the brakes. Driving with Eyesight is an INVOLVED experience. You have to know when to rely on it, when to disregard it (in the case of lane changers), and when to intervene.

I'd rather they first fix the auto braking when a car has departed a lane. On more than one occasion a car far head of me had moved to the left hand turn lane, but the Ascent is still tracking it then decides to slam on the brakes as I get near. This is with well defined lines and everything on the road. Far more dangerous to randomly apply the brakes IMO than to default to a state where a driver is in full control.

I agree it’s annoying like the fake shifts. I’ve learned to anticipate this auto braking and just override it by applying the gas a little until the little green light blinks or goes off.
Similarly I’ve had pre-collision throttle management prevent me from accelerating when changing lanes. I’ve also learned to get past that point where eyesight still sees that vehicle more quickly.

I should clarify this is a problem i am experiencing when using ACC and relying on it to maintain following distance.

@Robert.Mauro have you experienced this? do you have any tips/hacks?
I'm trying to determine if the on screen notification for a car coming into a lane are late.

As for a vehicle departing, sadly, the system won't accelerate until the departing vehicle is clear of the lane or very close to it.

It's a very hard thing for a computer to determine. Think of it this way, the car in the next lane swerves toward the line. Does the computer slow down then? If so, you'd be slowing down in traffic a lot! How about when it crosses the line? That would reduce it somewhat, yes but you would still get false slowing. Remember it's an adaptive cruise control system and an automatic braking system. It's not a Full Self Driving system.

I'm thinking technically that the system probably picks it up when it registers on both cameras fully and the computer can calc the distance correctly. The Tesla3 can do a better job at detecting that sort of thing as they also have radar sensors and 2 cameras in the side mirrors. Basically a whole lot more sensors with a whole lot more signal processing. And they still don't have theirs working either!

I finally managed to remember to upload my dashcam video of an example of what I’m used to seeing as a typical ACC response to lane changers. Watch the green light near the bottom left and listen for the beep. (Hope you like the radio music too!)
The Mustang comes into my lane from then left the moves one lane to my right. EyeSight picked it up pretty quickly coming into my lane. Had he been closer it may have slowed me down but didn’t need to. And as usual it doesn’t lose the Mustang until it’s nearly completely out of my lane.
I assume this is typical response. Can anyone else confirm or have you seen anything different.

Last night on the freeway, a small slow moving car changed lanes into my lane. I was going about 65 and the other car about 55-60. I saw him just starting to move but I wanted to see how Eyesight would respond. From experience I knew Eyesight was going to have an issue.

I let the car proceed with the Adaptive Cruise engaged. The car in front got 3/4 of the way in front of me, and my car got VERY close to his bumper, before I had to hit the brakes gently. My wife was screaming at me "what are you doing? Don't you see that car?"

So YES, Eyesight has a problem with cars changing lanes into your lane. You the driver, have to be ever vigilant.

That's exactly what I have experienced. One thing i wonder is if my ez pass placement had something to do with it. It is currently right behind the rear view mirror on the left side, below the dots. I now realize that it could be blocking the left side eyesight camera at certain angles. @TheLex is yours also mounted there?

@nycascender Try moving it up to the headliner over the dots. The black dots on the windshield don't affect the ez-pass operation. I keep it there right against the rearview mirror cableway so I can flip the HOV switch when needed and while its not recommended by Subaru to have anything there it doesn't seem to affect my EyeSight. My dashcam is in the same location on the passenger side.
