Comfort and Convenience
Cabin temperature is a personal setting rather than a fixed ideal. One person runs the air cool and brisk, another finds the same air chilly, so households sharing a car usually settle on a negotiated middle.
Safety and Driver Assistance
Preparation is simple: adjust mirrors, seat and climate while still parked, and check that the handbrake and gear selector behave as expected. Settling these at a standstill keeps attention on the errand once the car moves.
Multimedia and Connectivity
Calls arrive mid-errand, rarely at a convenient moment. Where hands-free telephony is set up, answering is a button press rather than a rummage through a pocket; otherwise the sensible choice is calling back once parked.
