Comfort and Convenience
Cabin temperature is the classic point of disagreement. What feels pleasant to a driver in a jacket can read as cool to someone sitting still behind, so travellers usually end up negotiating rather than agreeing outright.
Safety and Driver Assistance
Locating the demister, hazard switch and headlamp control while still parked is worth a minute, especially in a car that is new to you. Preparation simply means less searching later, when weather or traffic changes mid-journey.
Multimedia and Connectivity
Keeping a phone charged is a need in its own right, distinct from taking calls or playing music. Where a charging point is provided, its position quietly decides which occupant can actually reach it while under way.
