Comfort and Convenience
A slow street can feel pleasant with a window cracked for moving air, yet the same stretch can feel better with the glass fully shut. People simply differ in how they treat breeze and outside noise.
Safety and Driver Assistance
A damp school-run morning is a useful moment to already know the demister and washer buttons, because those controls then need no last-minute search.
Multimedia and Connectivity
Hearing a caller clearly while parked outside a shop is a practical need on errands. If cabin audio can carry a voice, that function stays separate from charging or music.
