Comfort and Convenience
Keyless entry matters at the moment of approach: the car recognises the fob in a pocket, so the door unlocks on a touch of the handle with both hands still full.
Safety and Driver Assistance
After a steering input that the car does not match, ESP compares the requested and actual path and brakes individual wheels to pull the nose back onto the intended line.
Multimedia and Connectivity
The audio system supplies the playback and amplification stage: it selects the source, sets volume and tone, and feeds the cabin speakers, whatever device is connected.
