I set it to the maximum closeness and its still enough gap for cars to just dart in front of you.

 

Any gap can be enough for cars to dart in front of you. At least with ACC, it slows your truck a little so you aren't in the bumper of the a-hole in front of you. Sometimes, you just have to let them go and back off. Driving a 9000lb truck requires the maturity and patience to NOT follow too close. You can't beat physics - it takes a lot of energy to slow 9000lbs. Don't use the frame of the car in front of you to absorb that energy.

 

Sorry, I don't think the Ford lawyers wanted them to design a system that would ride people's asses and then slam on the brakes if that person stopped.

I watch people swim in and out between cars with BARELY more than a foot between them and BOTH the car in front of them and the one in back of them.

What, exactly, are you expecting?

 

Really? I'm an avid manual reader. Did I miss this? If so, that's a cool feature. I haven't tried messing with ACC while towing, does it graphically show you it lengthens the following distance when you hit tow haul or how do you know?

 

And idiots like this are why we have people then braking, causing the chain reaction of everyone else braking which causes traffic!

 

I don't recall where the info came from - it may have been an old post on this forum. You can prove it to yourself going down the highway, though. The other day I was behind a car on a two lane and seemed to be farther back than normal. Thought the truck was just adjusting, but even after a few miles I was still further back than normal. Cursed the truck for a second, then noticed I was in tow haul (from a steep downhill about 30 mins prior). Clicked tow haul off, and truck closed up to the "normal" following distance. (No change in the indication on the dash)

 

And I agree 100% with this post.

So after I posted, I asked my wife who was with me to describe what it did the first time I tried using it. We were going across the one lane highway 37 towards Sonoma Raceway. Once you get to the track there's a light. I told her the truck was slowing down as we got to the light and I said look I'm not even touching the brakes. She was a little nervous. So I wanted to see what happened as we got to the light. Sure enough, the light turned red the car in front of me stopped and the truck stopped. I was blown away. Oh I did have my foot planted right above the pedal. Anyway, once the light turned green and the car moved the truck did. The wife said that was what she remembered. I will try it again and see what happens. Honestly, maybe we aren't remembering completely how it happened.

 

Mine will stop completely, but not re-start.
