Comfort and Convenience
Cabin temperature is a matter of taste rather than a fixed setting. One person wants air moving constantly, another finds the same airflow too much, and clothing, weather and how long the trip lasts all shift the preference.
Safety and Driver Assistance
A car that is new to you rewards a few unhurried minutes in the driveway: mirrors set, seat settled, indicator and wiper stalks identified. Preparation done at rest need not be repeated in motion.
Multimedia and Connectivity
Errands often bring calls at awkward moments. Where a hands-free arrangement exists, a conversation can continue without the phone in hand; whether music plays or the battery charges are unrelated matters.
