Comfort and Convenience
Seating position is personal: height, arm reach and preferred posture differ from one person to the next, so a single setting rarely suits two drivers who share the same car.
Safety and Driver Assistance
Knowing where the hazard lights, demister and wiper controls sit is easier to learn while parked than in traffic. A calm few minutes before setting off leaves less to work out at a wet junction.
Multimedia and Connectivity
Phone batteries drain quickly when navigation runs for a whole trip. Where a suitable power socket is available, keeping a matching cable in the car covers longer errands without a search for one.
