Comfort and Convenience
Seating position is a common example: some people prefer sitting high with a clear forward view, others lower and more reclined. Height, leg length and driving habits all shape that choice.
Safety and Driver Assistance
Learning where the lights, wipers and mirror controls sit before setting off means less searching later. A few minutes stationary, reading the handbook and trying each switch, makes the first drive calmer.
Multimedia and Connectivity
Keeping a phone charged during long trips is a separate question from playing music or taking calls. If a charging option is available, check that it suits your cable and phone.
