Comfort and Convenience
Preferred cabin temperature varies widely: what one person finds pleasant, the passenger beside them calls stuffy or chilly. Clothing, whatever they were doing beforehand and plain personal tolerance all pull the ideal setting in different directions.
Safety and Driver Assistance
A few minutes stationary, spent locating lights, wipers, demist and the hazard switch, means those functions can be reached later without a hunt. Such preparation costs little and is worth repeating in any car that is still unfamiliar.
Multimedia and Connectivity
Battery level matters on errand days, when a phone runs maps between stops. If charging is available on board, it answers that need alone; calls and music rest on separate arrangements and are each worth checking individually.
