Though I read the BMW just packed the high-end one in all cars at the beginning to streamline manufacturing, not sure whether that is still the case.

You are right

5DF is limited to 160 km/h. 5AU - to 210 km/h. Other than that, 5DF appears quite OK for 450€. 5AU costs 2000€.

For G30, 5DF costs 1200€. For G01, 5DF costs 900€. But, they are limited to 210 km/h - not 160 km/h like G20.
For me, lower cost and 160 km/h limit is quite fine compromise. You can add 5AU if you really need 210 km/h.

5DF Active Cruise Control

Camera and radar-based driver assistance system consisting of cruise control with approach control, Speed Limit Info incl. no-overtaking indicator, manual Speed Limit Assist, front collision warning with brake intervention.

Cruise control with approach control enables:
- regulation of distance from vehicle in front by radar sensors in the bumper
- automatic maintenance of queue speed and distance in stop-and-go traffic and in traffic jams, right down to complete standstill Automatic pull-away after short stops (1–3 s)
- Operation of the active cruise control via multifunction for steering wheel. Desired speed (30-160 km/h) and distance (4 steps) adjustable.
- function also detects stopped vehicles as target objects
- switch to 'Cruise control' without approach control possible.

- Speed Limit Info incl. no-overtaking indicator with display of speed limits further ahead and no-overtaking indicator

- (manual) Speed Limit Assist:
The Speed Limit Assist function combines Speed Limit Info with active cruise control and enables the predictive adoption of a detected speed limit into the Active Cruise Control (ACC) via an additional operation step.

Front collision warning with brake intervention consisting of approach control warning with braking function, person warning with city braking function and adaptive brake assist enables:
- situation-dependent pre-filling of the brake system and lowering of the trigger threshold of the 'brake assist' to provide maximum braking power in situations where collisions are likely.
- Reaction to vehicles ahead in a speed range of 5–200 km/h
- Reaction to stationary targets at up to 85 km/h
- Reaction to cyclists and pedestrians in a speed range of 10–65 km/h

Please note: the system scopes contained in the optional equipment only provide assistance within defined system limits. It remains the responsibility of the respective driver to react to the actual traffic situation.
