Driver Assistance Package vs. Driving Assistance Professional Package

I shopping for a 2024-2025 xDrive40 or M50 and am looking for clarity on what these packages actually include.

DAP = Active Cruise Control (ACC) that is radar based and sets following distance to vehicle in front. Does this system work in stop-and-go traffic or does it shut off at lower speeds?

DAPP = ACC plus “Traffic Jam Assist” which controls steering/lane keeping below 40mph. This package also describes “Driving Assistance Professional” which seems to describe the same thing. Speed, steering inputs, etc and also mentions “Lane Change Assistant”. Is this just doing the same thing that “Traffic Jam Assist”’does, but at speeds above 40mph? Does this system allow true hands free?

I am having a hard time finding any cars that have DAPP, but have found a few that have the DAP, so I’m just trying to figure out what the difference would be and if the DAP is enough for me. I currently have an Audi with “Traffic Jam Assist” and use it often on stop/go traffic, but the steering input is not that helpful since it won’t let me go fully hands free.
