Comfort and Convenience
Seating position is a personal matter. Some drivers prefer to sit high with a wide view of the street, others lower and more enclosed; body proportions and long habit both play a part.
Safety and Driver Assistance
It is worth a minute before setting off to locate the essentials — lights, wipers, demister, hazard switch — and to set the mirrors. Preparation done while parked is preparation not attempted later in moving traffic.
Multimedia and Connectivity
A phone used for navigation drains steadily, so many drivers would rather it charge during the journey than after it. Where charging is available in the cabin, that function stays useful whatever else the phone is doing.
