Comfort and Convenience
Preferred seating position is personal: height, leg length and how upright someone likes to sit all pull in different directions, so two drivers rarely settle on the same setup. In a shared car the difference shows up whenever drivers swap.
Safety and Driver Assistance
Spending a moment before setting off — mirrors, lights, wipers, hazard switch — is cheap preparation. Sorting it while stationary means one less unfamiliar thing to hunt for later, when the road is asking for your attention.
Multimedia and Connectivity
Charging is the phone need that bites most often: navigation drains a battery quickly, so where power is available matters on long days. Calls and music raise separate questions and are worth checking individually.
