Comfort and Convenience
Seating position is a good example: height, build and the length of a typical journey all shape where someone wants to sit. Two people in the same car often settle quite differently.
Safety and Driver Assistance
Adjusting mirrors, seat and climate before setting off takes a minute and saves fiddling later, when attention belongs elsewhere. It is also worth locating wipers and lights while stationary, particularly in an unfamiliar car.
Multimedia and Connectivity
Keeping a phone charged matters most when it doubles as the navigation screen, since a day of mapping drains a battery quickly. If a suitable power outlet is available, a cable within reach is enough.
