Comfort and Convenience
Seating position is a common example. Height, leg length and the way someone prefers to hold the wheel all shape what counts as a natural posture, so two people rarely settle on the same arrangement.
Safety and Driver Assistance
Spending a few minutes with the basic controls before setting off is simple preparation. Knowing where lights, wipers and demisting live means you are not hunting for them later, once the road is asking for your attention.
Multimedia and Connectivity
Keeping a phone charged through the day is a separate need from making calls or playing music. Where charging is available on board, its value lies in arriving with a usable battery rather than in sound quality.
