Comfort and Convenience
How open a side window sits on a short hop is a preference that splits people. Some like a little outside air and street sound, while others keep the glass up so a conversation stays inside the cabin.
Safety and Driver Assistance
On a dark morning, it helps to find the headlamp and wiper stalks while the car is still parked. Knowing which lever does which job means those controls are not being hunted once the journey has started.
Multimedia and Connectivity
On an unfamiliar errand, people often need spoken directions from a phone. If cabin speakers can play that audio, they may be used; the directions remain a listening task, separate from charging the handset or taking a call.
