Not great. If you come to a complete stop, it'll give you about a 2 second warning to put your foot on the brake (at which time it cancels ACC). If you don't, you'll just run into the car in front of you.
Good to know. If it's a less than 2 sec stop, or a near but not fully stop as you sometimes get in bumper to bumper traffic, is it relatively smooth? My reference point would be a modern Mazda's ACC, for what it's worth.
It's the only ACC I've used, so no frame of reference. It's pretty good if you don't come up on traffic that's moving way slower than you're going. Personally I like to slow down gradually, the ACC tends to wait longer and hit the brakes harder than I would do myself. Not terrible, but leaves a little to be desired.
I love it. So far ... it performs reliably when used at default sensitivity settings, and as per manufacturer specifications for acceptable performance and object detection (see manual).
This picture makes it look worse than it really is, at least if you're not really tall. Most will have a line of sight lower than the camera angle shown here.I was able to get a couple of pictures of the Wrangler with & without the ACC unit and then paste them side by side to get a better idea of what it looks like...
The line of sight is at eye level, it is what it is. Whether or not it's been "discussed" extensively is irrelevant. No one did a side by side comparison in a single photo & I simply posted it up there so anyone who can not visualize it perfectly in their head with words & opinions would be able to judge for themselves.
It works very well. I'm still hovering my foot over the brake pedal just in case but I've used it during highway traffic and most convenienntly during tunnel toll traffic. It does have a feature where it will warn you and eventually shut off if you are in stop & go for too long, and its not a terribly long timer (can't recall exactly how long) but just tapping the gas to "manual override" gently can reset that.
How would it run into the car in front of you if you have ACC? By default, that means you also have the FCW Active Braking, which would stop you from hitting anything in front of you.
Like the standard cruise control it's not advised to use it stop, and go traffic. It just becomes a PIA IMHO. My wife's car has the ACC, and I knew that any Jeep I bought would have to have that option. It's great, and as another said it takes a lot of stress out of driving. One of my problems is I find myself just riding along, and if I'm not paying attention I'll be traveling 5-10 under the speed limit because the car in front of me is going slower.
