Comfort and Convenience
Preferred cabin temperature varies from person to person, and passengers sharing a journey often disagree by a couple of degrees. Clothing, seating position relative to a vent, and habit all contribute.
Safety and Driver Assistance
Before setting off in a vehicle driven only occasionally, it helps to set the mirrors and check how the gear selector and parking brake operate while still stationary.
Multimedia and Connectivity
Taking a call is a different need from listening to music: one depends on clear speech in both directions, the other on sound quality. Hands-free functions, where fitted, typically share the same speakers.
