Comfort and Convenience
A seat that feels good for one person can feel unremarkable for another because body height, leg length and preferred posture all shape the sense of support.
Safety and Driver Assistance
Rehearsing where the wiper and light switches sit while the car is stationary saves awkward fumbling once traffic and weather demand quick reaction.
Multimedia and Connectivity
Keeping a phone charged on the move is often more about reducing worry over a low battery than about using it constantly. If the car supports a suitable power outlet, that need becomes easier to manage.
