Comfort and Convenience
Seating preferences differ because people vary in height, leg length and how upright they like to sit. A position that suits a tall driver can leave a shorter one reaching for the wheel.
Safety and Driver Assistance
Learning where the lights, wipers and climate controls sit is worth doing while parked, before setting off. Familiarity gained in advance means less searching for a switch once the car is moving.
Multimedia and Connectivity
A phone that runs low during a long drive needs power, which is separate from playing music or taking calls. If a socket or charging pad is available, topping up can happen regardless of how audio reaches the speakers.
