Whilst I believe the vehicle frontal collision protection on the F48 to be reliable (whereas the pedestrian protection came bottom of class in IIHS tests) , it is an assistance feature rather than a fail safe. Some owners report it randomly disconnecting or reacting inappropriately, some owners love it and others distrust it , there are a number of threads on this forum you can find and read.
The active cruise control With stop and go relies on same KAFAS camera and software as frontal protection although it also uses a sas module to boost processing power. The 5AT cruise control should keep a safe gap and even bring the car to a complete standstill where required however BMW still emphasise it is an aid and that the driver must be in control. In brief, it should react and brake hard but whether the system reacts quickly enough and firmly enough is down to you. I would suggest that in the event of seeing stationery traffic ahead, you hit the brakes. If the car has seen them first then still step-in and help, imho failure to do so could count as reckless/careless driving in the event of a wreck (and diagnostics can tell).
Anyhow, I wish you safe journeys always.
