Comfort and Convenience
Cabin temperature is a common point of disagreement: one person's comfortable setting feels cold to the passenger beside them. Agreeing a compromise early, and revisiting it as daylight changes, avoids repeated fiddling.
Safety and Driver Assistance
Learning where the hazard lights, demister and headlight switches sit is quicker in a parked car than in moving traffic. A few minutes before departure means less searching when a situation demands an immediate response.
Multimedia and Connectivity
Phone battery drains quickly when navigation runs all day, so a working charging arrangement matters more than on short trips. If a socket or cable port is available, keeping one lead permanently in the car avoids surprises.
