Comfort and Convenience
Preferred cabin temperature is a good example: one person sets it warm, another cooler, and a single setting rarely suits everyone aboard. Agreeing on it early tends to save repeated fiddling later.
Safety and Driver Assistance
Before setting off, a few moments spent locating lights, wipers and hazard controls is simple preparation, particularly in an unfamiliar car. Doing it while stationary means fewer decisions have to be made later.
Multimedia and Connectivity
Keeping a phone charged through a long day matters mainly for what happens after the drive, so where a cable sits and whether power is available on the move is worth knowing in advance.
