Comfort and Convenience
Comfort preferences vary because people have different sensitivity to cabin temperature and airflow, so one may want more air circulation while another prefers still, warm air.
Safety and Driver Assistance
Becoming familiar with basic controls before travel helps reduce the need to look away from the road for routine adjustments, such as wipers or defrost.
Multimedia and Connectivity
A common everyday need is keeping a phone charged during short trips, so having a usable power source nearby can prevent a low battery before the next errand.
