Comfort and Convenience
Preferred cabin temperature is a good example: some people travel comfortably a few degrees cooler than others, and airflow direction matters too. Body size, clothing and whether you are driving or resting all shift the answer.
Safety and Driver Assistance
Time spent before departure locating wipers, lights, demisting and hazard controls means you are not searching for them later. Preparation like this belongs with checking tyres and fluids rather than being left to the road.
Multimedia and Connectivity
A phone that stays charged through a long day is the basic need; a cable or wireless pad, if available, serves that alone. Hands-free calling and audio playback are separate functions with separate requirements.
