Now how hard will the brakes be applied? Is there a big rig 18 wheeler hauling gasoline behind you tailgating your azz? Now what if you were distracted or too relaxed and your reaction time, being so debilitated by the thousands or hundreds of hours or weeks and months of not having to worry about the braking problem, your reaction time was too slow or if you pressed the gas not enough and the gas hauler still hits you...
Or what if you hit it too hard and in fact the car in front did a double brake. They braked first in anticipation of a collision but they double guessed their initial reaction and then took their foot off the brake only to discover that they really needed to brake and braked hard the second time. By then you reacted and floored the gas pedal and rear end them.
ACC is a good theory but in practical everyday use it leaves much to unreliable on the table. It's an imperfect solution to an imperfect world. The problem is exacerbated when it's touted as a good or even great solution when it's a blatant defective technology. If it was more perfect then I'll will concede 100%.

I agree with you, the bottom line is you have distracted driving on both sides leading to terrible consequences. It just depends on where you want to put the responsibility/blame. But where I disagree, is that I recognize that situation B and C would have been avoided without the failure, and situation A could be avoided by actually paying attention. And I couldn't live with knowing that I (directly or indirectly) had anything to do with Situation B. At least in Situation A, its my own fault. In situation B or C, there I am fine and dandy, and then bam my life is ruint. But its ok, because some other distracted driver just avoided Situation A (and avoided the responsibility of actually paying attention). Welcome to 2016 America.

I would argue situation B and C would be avoided by paying attention as well. And here is where the actual problem lies. People are crappy drivers and don't pay attention. Those of us who do are a rare breed nowadays. People follow too close, change lanes without signaling and/or little to no space, text while driving and worry about other stuff instead of driving. Of course I have always been of the opinion that anyone caught texting in a moving vehicle be stripped of their license and the vehicle crushed into a little cube.
I see an opportunity here. Develop a rear facing technology to compliment the ACC. Shoot a too closely following vehicle with an electrically disabling charge (like a TASER for cars) if it gets within XXX feet.

Must be a Livonia thing, I don't think they have those around here. LOL
That to me would be working as intended. The cases I'm talking about the truck isn't following at the set distance the turning car is further ahead then that. So it's more like I see the car is turning, the car is almost out of the road and the truck gets within the ~100ft of the car and activates the red warning lights on the dash and hits the brakes hard. The times this has happened to me have been between 25 and 50 mph. I can easily tell that the vehicle is moving out of my path, but the truck sees it as a immobile obstacle.
My truck also doesn't "floor" it to get up to speed, the ACC accelerates like a grandma on Sunday.
The ACC was following the car at the set distance,, notices it slowing down so to keep the set distance it starts slowing the truck, then it sees we are still closing in on the car so it applies the brakes, it has no idea what is happening other than the car it was following is now going really slow, so slow down even more,, then it's gone off the radar. ACC then floors the truck to quickly get back to the set speed..

Let me make sure I have this right... People that don't use it are telling the people that do use it how bad it is? And The people that do use it are telling the people that don't how nice it is to have it?
Now who do you think has the most experance using ACC and most able to state facts?

Yes that's what I was saying we can think the ACC can't it only reacts to input from the radar.

I assume you meant the Ford system just isn't that advanced or violent in braking? If so, please drive an affected truck before you make a statement like that. I've had the recall done on mine, but before I did, it braked hard enough to cause the seatbelt retractors to leave a mark on my wife's shoulder - without me ever touching the brake. This happened as we were transitioning into a tunnel on a bright sunny day with no one else on the road. Broken technology has nothing to do with 50 years of driving or having an SCCA racing license.
I agree broken technology has nothing to do with 50 years of driving, etc, and I've asked around in my area to see if I could find anyone who has had the problem as described (answer-it has slowed them down but not "slammed" (for lack of a better word) on the brakes. This is both 15 and 16 models. I believe there could be a real issue and Ford needs to address and correct it. While I am truly sorry what happened to your wife, I think had it been a real danger (rather than technology error) your view of it would be different. Doesn't mean I'm right and you're wrong.
I'm travel right now, but when I get back home, I'm planning on talking to the senior electronics tech to find out if the sensor's "aim" can be tightened up to cut off vehicles outside of the lane the truck is in.
And if I could, is it possible some of these cases are because one of the vehicles (either the 150 or the vehicle that triggers the system) is drifting out of it's lane? That honestly could be an explanation. I know I sometimes drift a bit while driving (wind, rough road, inattentiveness (I confess)) which could trigger the system.

The ACC is just another very useful tool that I use when driving. I know about the passing a tanker truck problem, I know about the overpass problem, I know about the tunnel problem. And I'm always ready!!
I don't worry about the guy tailgating me because I have moved out of his way long before he got close to me. And this is where the ACC is so nice to have,, as while my eyes are looking in the mirrors checking the traffic behind me the ACC is watching the traffic in front just in case the F150 in front of me is passing a shining tanker truck and his ACC slams on the brakes because he wasn't ready to overcome this known problem..

Let's say it's taking off faster than it needs too. Killing my gas mileage, so I normally hit the cancel button and then start tapping the set speed up button till I'm back to the speed I want. Makes driving the truck a lot of fun for me..
