Comfort and Convenience
Seating height preference is a good example: some people want a commanding view over traffic, while others prefer sitting low and enclosed. Body proportions and previously owned cars shape that taste more than any rule.
Safety and Driver Assistance
Learning where the lights, wipers and demister sit before setting off is simple preparation. Weather and traffic can change within a minute, and that is an awkward moment to start hunting for a switch.
Multimedia and Connectivity
Keeping a phone charged through a long day is a separate need from playing music. If a device is powering up while travelling, any navigation running on it remains available for the return leg.
