Comfort and Convenience
Cabin temperature is a personal setting rather than a fixed one. Clothing, time of day and individual sensitivity to warm or moving air all pull in different directions, which is why passengers often disagree.
Safety and Driver Assistance
Anything adjusted while stationary, from seat and mirrors to climate and route, need not be adjusted in motion. Drivers returning to a car after a gap benefit most, since habits fade faster than people expect.
Multimedia and Connectivity
Calls are the part of a journey that cannot easily wait. If hands-free calling is available and paired in advance, answering becomes a single deliberate action instead of a search through pockets.
