Comfort and Convenience
Cabin temperature is a good example of how preferences diverge: some people want steady warmth, others prefer cooler air moving around them. Passengers sharing the same space often settle on a compromise.
Safety and Driver Assistance
Adjusting seat and mirrors while stationary is easier than doing it in traffic, and the same is true of learning which stalk does what. Unhurried preparation keeps small tasks out of the way later.
Multimedia and Connectivity
Taking a call without holding a handset is a practical concern for anyone who drives for work. Whether that is possible depends on the equipment present, and it is a separate matter from audio playback or charging.
