Comfort and Convenience
Preferred cabin temperature is personal. Build, clothing and how long someone has been sitting still all change what feels pleasant, so two people travelling together often want different settings from the same journey.
Safety and Driver Assistance
A moment before setting off is a good time to locate the essentials: lights, wipers, hazard switch, mirrors and seat position. Preparation made while stationary is preparation that does not have to be improvised in traffic.
Multimedia and Connectivity
Keeping a phone charged is a separate need from making calls or playing music. Where on-board charging is available, it matters most on long drives when navigation runs continuously and the battery drains through the journey.
