Comfort and Convenience
During a stop-start school run, some occupants like more cabin warmth while others prefer cooler air, because temperature comfort is a personal preference rather than a shared rule.
Safety and Driver Assistance
On an early airport run, locating the lights, wipers, and heater controls while the car is still parked avoids searching for them once you are already on the road.
Multimedia and Connectivity
Taking a short work call in a supermarket car park is easier if a speaker function is available, because you can talk without holding the handset.
