Comfort and Convenience
Cabin temperature is one of the clearest examples of differing preferences: a setting that suits one person can feel too warm or too cool to a passenger sitting alongside.
Safety and Driver Assistance
Drivers in an unfamiliar car often reach for a stalk by memory from another model. Trying the indicators, horn and hazard switch beforehand replaces that guesswork with something already known.
Multimedia and Connectivity
Taking a call differs from listening to music, since a call needs a microphone and the ability to answer without handling the phone. If hands-free functions are available, that difference matters most.
