Comfort and Convenience
Seating position is a personal preference rather than a fixed standard, since height, leg length and driving posture differ. A setting one person finds natural can feel too upright or too reclined for another.
Safety and Driver Assistance
Learning where the lights, wipers and demister sit before setting off can mean fewer glances away from the road later. Familiarity is easiest to build while parked, when there is no traffic to follow.
Multimedia and Connectivity
Keeping a phone charged on a long day matters separately from playing music or taking calls; a battery may drain even where audio is handled some other way. Each need is worth considering on its own.
