Comfort and Convenience
Preferred cabin temperature is a good example. Some people travel warm, others want cooler air moving, and it differs because clothing, time of day and personal sensitivity vary, so any setting suits one occupant more than another.
Safety and Driver Assistance
Spending a moment before setting off to locate lights, wipers and demisting controls means less searching later. Familiarity is simply preparation: the first time you need something is rarely the best moment to learn where it lives.
Multimedia and Connectivity
Keeping a phone charged on longer days is its own need, separate from calls or music. Where a suitable power source is available, a cable that reaches the usual resting spot matters more than headline features.
