Comfort and Convenience
Cabin temperature is the clearest example of a preference that never settles: body size, clothing and how long someone has been outside all change what feels right, so the setting that suits a driver often suits nobody else.
Safety and Driver Assistance
Learning where the lights, wipers and hazard switch sit while the car is still parked is simply preparation: it removes one thing to work out later, when weather or traffic gives less room for searching.
Multimedia and Connectivity
A phone that arrives home with charge left is the practical need on errand days; if a charging point is available it covers that, while calls and music are separate matters handled by whatever audio arrangement the car offers.
