Comfort and Convenience
Cabin temperature shows how personal comfort really is: the setting one occupant finds pleasant feels stuffy to the next. Clothing, build and how long the journey has run all move where people want it.
Safety and Driver Assistance
A minute before setting off, spent locating lights, wipers, mirrors and the hazard switch, means none of them has to be hunted for later. That kind of preparation is worth repeating in any unfamiliar car.
Multimedia and Connectivity
Keeping a phone charged across a long drive is a separate question from playing music or taking a call. Where a charging point exists, knowing its location in advance saves rummaging; audio sources are handled elsewhere.
