Adaptive cruise control: How close can it be set to the car ahead?

[JEDI]

it's nighttime and traffic is moderate. you're barely at the speed limit.
this suv behind me gets close enough that i cant see it's headlights.

traffic becomes looser and i am now 10mph over the speed limit and he's now following at a normal distance.
there's a red light and we stop.
again, he's now so close that i cant see his headlights.

the light turns green, i accelerate slowly and he's still on my tail till about 5mph over the speed limit.
then there's space between us.

wtf?
adaptive cruise control?

I doubt it as any ACC system I've seen will not let you get that close. The minimum is usually at least a 1 sec or 1 car gap. It's more likely that that is just the way they drive.

Agreed.

The adaptive cruse in my F-150 will bring me to a stop right behind a vehicle in front of me at stop signs/lights, or in case of an impending collision. (pre-collision assist)

That's ACC with additional stop and go function. After you're moving what is the minimum distance your ACC will let you get near the driver in front of you?

The minimum distance can be adjusted, and also will vary with speed. (see post 2). I have eyesight, the Suburu system. It will bring you to a stop very close to the car in front of you, but will shut off then, so you have to re-engage when traffic starts moving again. Some newer systems or those on higher end vehicles may take car of this automatically, IDK.

As ondma says, the distance is variable...and speed dependent.

Maybe I didn't phrase my question very well. After you're moving and negating the stop and go function of your ACC system, what is the minimum distance you can set your ACC? I assumed you made your post to relate how the vehicle in the OP stopped very close to him at a red light. What I was trying to get to was that after you're moving the ACC has a minimum distance for a user setting which is usually at least 1 car or 1 sec. Which wouldn't allow the vehicle to tail gate him after they moved from the red light. Maybe you meant something else in your post, I'm not sure.
