Comfort and Convenience
Cabin temperature suits people differently: a setting that feels pleasant to the driver can seem chilly to a passenger who has been sitting still. Shared journeys usually end in a compromise somewhere between the two.
Safety and Driver Assistance
A few minutes stationary is a good time to locate the hazard lights, demister and horn. Learning where they are while parked means less hunting later, especially in a car that is new to you.
Multimedia and Connectivity
Phone battery matters on long drives, since navigation drains it quickly. Where a car offers a USB socket or twelve-volt outlet, topping up en route is simple; otherwise charging before departure is worth planning.
