Comfort and Convenience
Seating position is personal. Taller drivers often want more distance from the wheel, while others prefer sitting high for a clearer view of the road ahead, so the same arrangement rarely suits two people equally.
Safety and Driver Assistance
A few minutes before setting off are well spent locating the hazard lights, the demister and the mirror adjusters. Sorting this out while parked means fewer things to work out later, when attention is better spent elsewhere.
Multimedia and Connectivity
Keeping a phone charged on longer trips is a common need; where a suitable power outlet is available, a cable can top up the battery during the drive. Calls and music are separate questions again.
