Comfort and Convenience
Comfort preferences vary because people and journeys do. Height, reach and the angle someone likes to sit at differ from driver to driver, so a position that suits one person can feel wrong to the next.
Safety and Driver Assistance
Setting the mirrors, noting where the lights and hazard switch sit, and settling the seating position takes a moment while still parked. Doing it then leaves fewer unknowns to work out once traffic is moving.
Multimedia and Connectivity
Phone battery is the common everyday concern, since a long drive drains it steadily. Whether charging is possible on the move, and where the handset rests while it happens, is worth establishing in advance.
