Comfort and Convenience
Seating preferences vary because people differ in height, leg length and how far ahead they like to look. A position that feels natural for one driver can leave another reaching or sitting too low.
Safety and Driver Assistance
Finding the wiper, light and hazard switches while parked means they are already familiar when conditions change. Sorting this out before setting off leaves fewer things to work out once the car is moving.
Multimedia and Connectivity
Battery level matters on longer journeys, since a phone used for navigation drains quickly. If a charging point is available, a cable of the right type still needs to be carried.
