Comfort and Convenience
Seating height is a good example: some people want to sit low and enclosed, others prefer a raised view over the bonnet. Height, leg length and driving habits all pull that preference in different directions.
Safety and Driver Assistance
Locating lights, demisters and hazard switches while parked means you are not searching for them when conditions change. Preparation of this kind takes a couple of minutes and only needs doing once per car.
Multimedia and Connectivity
Keeping a phone charged on long days matters most to drivers who navigate from it, since a flat battery ends the route. If a charging point is available, its position decides whether the cable stays out of the way.
