Adaptive Cruise about caused wreck...

jschira - the adaptive cruise does do the same thing everytime it's in the same situation.. that's the beauty of software (provided it's well written). The "getting used to it" part is just learning how it views those different situations, and understanding the logic process it take in each situation.

And what if the situations are not exactly the same (which they rarely are). So take the situation where a car cuts across the lane in front of me. Sometime it passes 10' in front. Sometimes 15', etc. Sometimes the car might cut across quickly, sometimes it might linger for a few seconds.
My dumb cruise control does exactly the same thing, every single time. No learning curve. More importantly, I only have to do one thing (hit or tap the brake pedal) every single time. It becomes second nature easily.
I'm not saying that these features will not get to where they need to be sometime in the future, and you have to start somewhere.

If the car cuts across in front of you and keeps going the adaptive cruise wont do anything it thinks a bit before it reacts in that case, not sure how many seconds but it doesn't do anything, and it gives you time to be ready for it to slow down if there is no one behind you just let it do its thing if there is someone behind just have your foot on the throttle so your car cant slow

Just like all the electronics in aircraft some of the newer pilots are relying on it too much and can't even navigate if something happens, you still need to be able to override it and do what it wont, I.E. another plane crosses in front of you the autopilot wont try to avoid it , it is up to the pilot to take command from the aircraft and fly the plane.

I have been thinking about this and similar comments and I ask the question, "why do I have to get used to it"?
I drive old Fords with 4 wheel manual drum brakes. Often after replacing the brakes, the car will pull to one side or the other. Sometimes only mildly, sometimes very badly. Sometimes the pull goes away as the shoes lap into the drums and/or the adjusters on all 4 wheels tighten up. Sometimes the pull gets worse.
After a while, if the pull does not go away, I get "used" to it and can anticipate where the car is headed when I hit the brakes.
But does this mean that I do not fix the problem? I don't think so.
When I hit the brakes, I do not want to guess what the car is going to do, even if I get pretty good at guessing correctly. I want the car to stop straight and true, every time. If it does not, then I need to fix the brakes.
Same goes for the cruise control. I do not want to have to out-guess the software, trying to anticipate having to do "A" in situation "X" or do "B" in situation "Y". I want the car to do exactly the same thing every time, time after time. In my case, with "dumb" cruise control, the car is going to keep going at the speed that I selected unless I, or something else, stops the car. Maybe not very "smart", but very predicable.
PS - Car and Driver a while back tested a Jaguar with adaptive cruise control. It had the same problems going around curves (2 lane and 4 lane) as described herein. C&D got so frustrated that they turned the CC off.

Similar to a TV remote control, the remote works correctly once you realize how to operate it and point it towards the device you wish to operate. We need to learn how to use adaptive cruise control and its limitations at this stage in its development.

Just like the lane guidance, keeping system also has limitations. I have found the driving into the sun early morning or evening the camera cannot "see" the lines and the system is disabled. Also on rainy nights where the headlights reflect off the water or the lines are hidden in the water the system disables as it cannot "see" the lines.

It does apply the brake lights at any time the vehicle's brakes are applied, no matter how lightly.

The reason you need to get used to this technology is so you can understand its limitations. It is not broken as in your "drum brake" example, more that it is limited in its ability to function.

Finally, there is an awful lot less at stake when you don't aim your remote correctly...

Sorry, but this does not sound like a labor saving device to me.
I guess that I am not just an early adopter. You will not see in line in front of the I-Phone store at 1 AM.

So now you are saying that ACC might do something or it might not? And that it might take several seconds to make up its mind?

In reality, it is a very simple system.

My wife's 2008 & now her 2016 Toyota Sequoia Platinum has Laser Cruise and I've experimented with it multiple times by pushing it to the limits. I've let it "see" a 45MPH semi in front of me as I was approaching at 75 MPH - Hovering over the brakes and ready to take evasive maneuvers. Sure enough, as soon as the truck was detected, the CC slammed on the brakes. Although there was no traffic behind me at the time, it made me wonder if the brake lights were activated.
Besides what the OP experienced, I've learned that there are multiple other situations where although this technology works, it may not always operate smoothly. In the situation above, what would have been a simple, routine lane change for an attentive driver was turned into a near violent emergency slamming on the brakes by the CC.

By the way, experimenting I allowed (with my foot ready) the ACC to follow traffic all the way into a town, 65 to 55 to 45 to 35 to a stop light. I slowed about the same way I would have slowed considering the traffic and ACC brought the truck to complete stop where it then completely disengaged/turned off.
I did the same again where traffic did not come to a complete stop and it followed everyone in and through another town returning me to highway speed.

I am thinking that this issue has been discussed thoroughly enough for everyone to make up his/her own mind.
Personally, I probably would not use it, and I certainly would not pay extra to get it if I could avoid it.
But I drive 2 different pickups with no cruise at all, crank up windows and manual push button locks, so no one really should listen to me.
