Comfort and Convenience
Seating preference is personal. Some drivers sit upright and close to the wheel, others further back with arms extended, so the same cabin ends up arranged differently by each person who regularly uses it.
Safety and Driver Assistance
Learning where the lights, wipers and hazard switch sit while the car is still parked means less searching later. Preparation here is simply knowing the routine before weather or traffic makes it urgent.
Multimedia and Connectivity
Keeping a phone charged through a long trip is a separate need from playing music or answering a call. Where a socket or port is available, it helps to plan in advance where the cable will run.
