Comfort and Convenience
Seating preference is personal: height, arm length and driving habit all shape where someone wants to sit. Two people sharing a car across a long route rarely settle on the same position.
Safety and Driver Assistance
The few minutes before departure are the natural time to locate hazard lights, demister and headlight settings. Doing that while stationary means an unfamiliar switch is not being hunted for in moving traffic.
Multimedia and Connectivity
Phone battery tends to be the constraint on a long day, since navigation draws on it steadily. Where charging, hands-free calling or audio playback are available, it helps to confirm how each is set up beforehand.
