Comfort and Convenience
Cabin temperature is a common point of disagreement, because people differ in build, clothing and how much they move during a journey. A setting one passenger finds pleasant can feel too warm or too cool to another.
Safety and Driver Assistance
Time spent before setting off, locating lights, wipers and mirror adjustment while stationary, means these things are not being learned in traffic. Unfamiliar cars and shared cars make that short check worthwhile.
Multimedia and Connectivity
Keeping a phone charged is the need that usually comes first on longer trips, since navigation drains a battery steadily. Where charging is available in the cabin, it is worth knowing which seats can reach it.
