Comfort and Convenience
Cabin temperature is a common example. One person prefers a cool draught, another warmth around the feet, and those preferences follow clothing, the season and plain personal habit, which is why travelling companions rarely agree.
Safety and Driver Assistance
Before setting off, it is worth a moment to locate the essentials: lights, wipers, mirrors, the hazard switch. Doing this while stationary means nothing needs hunting for later, when a driver would rather be looking ahead.
Multimedia and Connectivity
Keeping a phone charged on a long drive is a practical need by itself, separate from making calls or choosing music. Where a charging option exists, what matters is that cable and holder obstruct nothing.
