Comfort and Convenience
Cabin temperature is the classic example: one person sets it low to stay alert, another finds the same setting cold. Height, clothing and where you sit all change what feels right.
Safety and Driver Assistance
Learning where the hazard switch, demister and headlight controls sit is a five-minute job best done while parked. Searching for them in rain or heavy traffic is the situation worth avoiding.
Multimedia and Connectivity
A phone used for navigation drains steadily, so a long drive usually means keeping it powered. Where a charging option is available, that is separate from whether calls or audio are handled.
