Comfort and Convenience
How much fresh air people want through an open window is a comfort preference, and it often depends on whether they enjoy a breeze or find moving air distracting.
Safety and Driver Assistance
Time with the gear lever, indicators, and lights while parked is useful preparation, because those controls are then already known at the first junction.
Multimedia and Connectivity
Hearing a podcast on the school run is a common listening need, and if audio playback is available it can run independently of taking a call.
