Comfort and Convenience
Seating position is personal: people differ in height, reach and how upright they like to sit, so a setting that suits one driver feels wrong to the next. In a shared car, the first minute often goes on readjusting.
Safety and Driver Assistance
Before setting off, it helps to know where lights, wipers and hazard switches sit. Finding them once while parked means they can later be reached without hunting through unfamiliar positions mid-journey.
Multimedia and Connectivity
Battery level is the usual city worry, since navigation runs for the whole trip. If a car offers a way to power a phone on board, the point is arriving with charge left rather than rationing it.
