Comfort and Convenience
Seating preferences are personal: height, build and driving posture all differ, so a position one person finds natural can feel wrong to the next. That is why the same car is set up differently by each driver.
Safety and Driver Assistance
Learning where the basic controls sit before setting off is simple preparation. Hazard lights, demisting and wiper operation are easier to find while parked than while moving, especially in an unfamiliar or borrowed car.
Multimedia and Connectivity
Keeping a phone charged on the move is its own need, separate from calls or music: a navigation app drains a battery quickly, so where a charging point is available, a long journey ends with a usable phone.
