Comfort and Convenience
Cabin temperature preference differs on a rainy school run: some people like a warmer cabin, while others prefer cooler air, and that choice is simply personal.
Safety and Driver Assistance
Checking how the indicators and horn work in a quiet car park is useful preparation, because those controls are needed as soon as traffic appears.
Multimedia and Connectivity
A missed call during a supermarket wait is easier to return if a speaker function is available, because the phone can stay in a bag rather than being held.
