Comfort and Convenience
Cabin temperature is a good example: some travellers want steady warmth, others prefer cooler air moving constantly. Build, clothing and how long someone has been seated all shift the preference, so agreeing a setting early avoids repeated adjustment.
Safety and Driver Assistance
Before setting off, it is worth locating wipers, lights, demisting and hazard switches while stationary. Doing this calmly in a parked car means no searching later, when attention is better spent on the road ahead.
Multimedia and Connectivity
Keeping a phone charged matters most on long days, since navigation drains a battery steadily. A charging point, however it is provided, is a separate question from whether calls or music are routed through the audio system.
