Comfort and Convenience
People settle on different cabin temperatures, and passengers sharing one car often disagree. Preferences shift with clothing, time of day and whether someone has just been walking outside in the cold.
Safety and Driver Assistance
Before setting off in a car you rarely drive, it helps to locate the indicator stalk, demister and mirror adjusters, since reaching for them later divides attention between two tasks.
Multimedia and Connectivity
Using a phone for navigation drains its battery quickly, so charging is worth planning separately from audio. Music playback and call handling may each work over a different link.
