Comfort and Convenience
Preferred seating position is personal: reach to the wheel and sightlines over the bonnet depend on height and build, so a setting one driver settles into quickly can feel wrong to another.
Safety and Driver Assistance
Learning where the essentials sit, lights, wipers, demisting and the hazard switch, is best done while parked. Anything found by memory later is one less thing to search for mid-journey.
Multimedia and Connectivity
Keeping a phone charged during long drives is a common need, and it is separate from playing music or taking calls. Whichever cable or socket suits the handset, a settled place to rest it helps.
