Not sure why you are downvoted. My Subaru does a pretty good job of detecting both moving and stationary objects, using only stereo cameras. It does have its limitations, and I wouldn't trust it to be a level 4 or 5 auto-auto without additional sensors. But it sure blows away Tesla when it comes to little things like detecting parked fire engines and highway barriers.

Seems like eyesight does a pretty good job at 35 mph, not so much at highway speeds.

Have you had any experience with eyesight helping at highway speeds?

Guess that depends on what you mean by "helping".

What you describe is specifically related to emergency braking. None of these systems claim to prevent collisions at high speeds through emergency braking. But they will significantly reduce the impact. No, I haven't tested that personally, and I don't plan to, so no actual "experience" there.

However, there are other aspects of EyeSight I do have experience with at highway speeds.

- Collision alert. It's an extra set of eyes to keep an eye out for trouble. When I'm checking over my shoulder before a lane change, I can take a little more time and look more carefully, knowing that it is watching the road ahead. It has alerted me for things like a car slowing suddenly or squeezing in front of me.

- Adaptive cruise. This helps by reducing load on me while driving and maintaining a safe following distance. So I can focus less on the car ahead and pay more attention all around.

Tip for users of EyeSight and other systems: Always remember that like every other system out there it's not perfect and has limitations. Don't get complacent. After 5+ years of driving with it, I'll still keep my foot ready to brake, even in situations I'm confident it can handle. Occasionally I'll give in to the urge to brake only to find that it has started braking by the time my foot hits the pedal. But I'd rather react too soon than wait too long.
