Comfort and Convenience
Preferred cabin temperature is personal: clothing, the weather outside and how long someone has been sitting all change what feels pleasant. Two people on the same journey often want different settings entirely.
Safety and Driver Assistance
A few minutes spent before setting off locating the hazard switch, the demister and the light controls is time well used. Preparation leaves fewer decisions to make later, when the road already asks for attention.
Multimedia and Connectivity
Keeping a phone charged across a long drive is a practical concern in its own right, quite separate from calls or music. Where a suitable socket and a resting place exist, the phone stays powered and reachable.
