Comfort and Convenience
Seating position is a personal preference. Drivers differ in height, arm reach and how upright they like to sit, so an arrangement one person settles into immediately can feel slightly wrong to the next.
Safety and Driver Assistance
Before setting off, it is worth knowing where the basic controls sit: lights, wipers, mirrors, demisting. Finding them from memory means less searching mid-journey, and that groundwork is most easily laid while parked.
Multimedia and Connectivity
Charging is a need of its own, separate from calls and from music. A long errand run matters less to a phone battery when the handset can be kept powered, whichever socket or connection is available.
