Comfort and Convenience
Seating position is a personal matter. Height, arm length and long-held habits mean two drivers rarely settle on the same distance from the wheel, which is why each person's idea of a natural posture differs.
Safety and Driver Assistance
Before setting off, it is worth locating the basics: lights, wipers, demisters and the hazard switch. Doing that while parked means the first time a driver needs one of them is not also the first time they go looking.
Multimedia and Connectivity
Keeping a phone charged across a long drive is a need of its own, separate from playing music or taking a call. Where a power source is provided and within reach, a passenger can handle it without rearranging the cabin.
