My driving style always gets well over 100K mile on a set of brakes.
This system (again great for Americans) probably contributes to the typical American brake life of 20K to 40K miles.

The thing about ACC is that yes, it sort of sucks in some ways, but you only need it about 1% of the time (or at least, I do.) And that 1% makes all the difference.
Just got back from a trip through LA on 405, for example, where two-hour stop-and-go backups are their idea of fun. ACC is a real sanity-saver under those conditions. Set for maximum following distance, select the 'Normal' drive mode (least aggressive braking), and you will rarely actually stop. When you do, it will take off automatically unless the stoppage lasts for more than 5-10 seconds or so, in which case you just need to bump the stalk upwards.
Same story on busy two-lane rural roads where passing isn't safe/possible. It just works.
If you are lucky enough not to ever encounter these situations then you don't need ACC, but for most drivers it is well worth specifying.

I love ACC and won’t own a car without it. The few times it brakes for someone cutting me off is minimal compared to manually turning it on and off again.
I can understand why you would want the option for using cruise without ACC and it should be an option.

I dunno. Whenever I use the cruise control in my 981 I have to force myself to repeat under my breath, "I do not have radar. This car will not stop itself." I can see a valid human-factors rationale for not supporting active and passive cruise in the same vehicle.
(That said, I have seen the 95B.2's cruise control enter 'Passive mode' on occasion, but I'm not sure what causes it to happen.)

All current assist systems need work but as long as you can turn the feature off I want it.
I’m at a certain age that I hope Level 5 autonomous driving comes sooner that later. :0)

Love Adaptive CC usually, but there have been a few very rare instances where it slams on the brakes. I know what causes it, so I have to turn it off when I see it coming.

The only calibration possible is to set the following distance as close as possible.

More distance, more chance for someone to cut in front of you. But I understand where you are coming from.
Porsche brakes are capable of handling the shorter stopping distances.
