Comfort and Convenience
Seating position is personal: height, reach and the angle people find natural vary, so two drivers rarely prefer the same position. The same applies to cabin temperature, which one passenger may want cooler than another.
Safety and Driver Assistance
It helps to locate lights, wipers, mirrors and the hazard switch while still parked. Looking for them later competes with traffic for attention, and a short pause before moving keeps that search out of the journey.
Multimedia and Connectivity
Phone battery is the usual city concern, since navigation runs throughout. If a car offers a charging point, the practical meaning is simple: the phone arrives usable, rather than needing attention at the end of the day.
