Comfort and Convenience
Preferred cabin temperature varies widely, because clothing, build and simple habit differ from one person to the next. Agreeing on a setting early in a shared journey saves repeated back-and-forth adjustment later.
Safety and Driver Assistance
Before setting off, it helps to locate things like the lights, wipers and demister while stationary. Finding them once, calmly, means less searching afterwards, when attention is better spent on the road ahead.
Multimedia and Connectivity
Phone charging is its own need, separate from calls or listening: a battery that lasts the journey matters either way. Where a charging point is provided, keeping a suitable cable to hand is sensible.
