Comfort and Convenience
Seating height is a good example: some people prefer sitting low and enclosed, others want a raised view over the bonnet. Body proportions and habit differ, so no single position suits everyone.
Safety and Driver Assistance
Wipers, lights, demisting and hazard switches are easier to find when you have located them while parked. A few minutes spent learning a layout means less searching later, when attention belongs on the road.
Multimedia and Connectivity
Battery level matters most on long days, since navigation drains a phone steadily. If charging is available, a cable or socket keeps the device usable; calls and music are separate questions from power.
