Comfort and Convenience
Seating position is a personal preference: height, leg length and driving habits mean two people rarely settle on the same setup. On a long trip, that preference matters more than it does on a short errand.
Safety and Driver Assistance
Knowing where the wiper, lighting and demister controls sit before setting off means less searching later. Preparation like this is easiest while parked, when there is time to read the labels properly.
Multimedia and Connectivity
A phone that still holds charge at the end of the day is the usual concern, since navigation drains batteries. If a charging option is available, a cable kept in the car saves improvising at a stop.
