Comfort and Convenience
Cabin temperature preference varies because a driver on a winter commute may want warmer air, while a passenger arriving from a heated building prefers it cooler.
Safety and Driver Assistance
Before an early airport run, locating the hazard switch and demister while still parked means you are not hunting for them later in traffic.
Multimedia and Connectivity
If the phone is used for maps on a day of appointments, charging it in the cabin, where that facility exists, keeps the battery from dying before the last visit.
