Comfort and Convenience
Some drivers like sunglasses on the dashboard for quick access, while others prefer them in a pocket or bag. The habit differs because people notice glare and clutter in different ways.
Safety and Driver Assistance
Before departure, it helps to find the window switches and the door-lock control so you are not searching for them at a barrier or ticket machine. That is ordinary preparation.
Multimedia and Connectivity
A common need is to take a short work call only after pulling into a service area. If a speakerphone function is present it can keep both hands free while parked; if not, the handset still works.
