Comfort and Convenience
Where a driver likes to sit is personal. Leg length, arm length and plain habit all differ, so a position that feels natural to one person feels cramped or too distant to another.
Safety and Driver Assistance
Locating the wipers, lights, hazard switch and demister while parked means you are not hunting for them later, when attention is already divided between traffic, a turning and the next stop on the list.
Multimedia and Connectivity
A short errand rarely adds much to a phone battery, so charging is about holding a level rather than filling it. Calls and music remain separate needs, and each may be handled differently.
