Comfort and Convenience
Seating preferences differ because bodies and habits differ: height, leg length and the way someone likes to hold the wheel all shape a chosen position. Sharing a car means revisiting that setting.
Safety and Driver Assistance
A few minutes before setting off, spent locating the hazard switch, demister and mirror adjusters, means those functions are already known when weather or traffic later asks for them quickly.
Multimedia and Connectivity
Keeping a phone charged through a long day matters on its own terms. Charging is separate from calls and from music, and each may be handled differently, so it helps to know which is available.
