Comfort and Convenience
Some people like a window slightly open for fresh air, while others prefer it closed so papers and clothing stay still. That preference differs because people react to moving air in different ways.
Safety and Driver Assistance
Knowing where the light and wiper stalks sit before departure lets you respond to dusk or rain without searching. A brief check of those basic controls is part of getting ready.
Multimedia and Connectivity
A passenger may want a familiar podcast for time on the road. If audio playback is available, that recording can run without handing the phone around the cabin.
