I have and never use it. I like have full control of car.

Exactly! Porsche makes this technology available in the 718 and 911 models, at significant cost to the buyer, because it has already been developed for their SUV and Panamera models. So for them it's pure profit for each 718 ordered with ACC.But why would you do that in a 718?
Could be that some systems brakes even if the system is not on.I'd heard a rumor that PAS/ACC is a no-no if you want to track the car. Like some clubs won't let you track at all if you have those options.
ACC on the 718 Cayman gives you two features both of which depend on the radar sensor located beneath the front number plate. The first feature is obviously the ACC itself, which allows the car to follow a car in front and brake down to a standstill (if necessary) and start off again. This is basically about stage 0.5 on the 5 stage car autonomy list - and this is about as far as Porsche have got so far. A standard Mini offers more.Could be that some systems brakes even if the system is not on.
My wife´s VW Golf does that if you push it hard in to corners and there is a guard rail, **** dangerous if you ask me...

Porsche ACC does not operate unless specifically selected - or, in my case, even when specifically selected. In other words it's OFF most of the time unless you manage to turn it on. No one in their right mind would turn it on when using the car on a track.
The other feature it offers is PAS (as I've said). This is ON all the time - according to Porsche anyway. I haven't yet been able to verify that, but I'll check it out because some of what Porsche say is not true in my experience. What this does is use the permanently active radar sensor to detect when the car is in danger of hitting the car in front and give an audible warning and prepares the brakes. If you persist in what the Porsche software thinks is dangerous driving it will give a jolt on the brakes. But it doesn't stop you - it just tries to make you aware of a possible problem. This seems reasonable to me.
Whether this actually works properly or not I have yet to find out. I can see the problems with the car taking control over from the driver because I was once given a Mercedes courtesy car which had a feature which tried to decide if you needed to an emergency stop by measuring how quickly you moved your foot from the accelerator to the brake. If you did it very quickly it immediately applied emergency brakes - which it did when I braked for roundabout. Seriously dangerous - they don't offer this feature any more. The Porsche's approach seems fairly cautious by comparison. My concern is that the PAS will kick in when I approach a corner - with a hedge behind it like a lot of country roads in the UK - at speed.
When I work out how to use it and the snow clears I'll report back.
The inability to turn it off is the problem, and why some clubs won't let you track a car with that feature. Unexpected breaking on the track is a really bad idea.The other feature it offers is PAS (as I've said). This is ON all the time - according to Porsche anyway.

You can barely see it unless you're looking for it. Get used to it because car autonomy is on the way - by legislation if necessary. I suspect that AEB (autonomous emergency braking) will become mandatory in the next few years. It's already on many cars, though not the Porsche. Everyone complained about seat belts when they were introduced but they don't complain now. They only have to save your life once for them to be worthwhile.The inability to turn it off is the problem, and why some clubs won't let you track a car with that feature.

Plus, that Cylon eye thing is hella ugly.![]()

For some, perhaps. For many aesthetes such as myself, it slaps me in the face when I see the front of a 718 with one on it. So while this may be true for you, it is not for me, @JakiChan, and others.You can barely see it unless you're looking for it.
If what happened in Arizona yesterday is any indication, maybe not as quickly as some think -- and certainly not as widespread as most think. This is not the place for a discussion of that, however, so carry on.Get used to it because car autonomy is on the way - by legislation if necessary.
You can't turn off PAS, and PAS is what gets you banned from the track.It appears that you can turn it off (from page 36 of the online manual):
