Comfort and Convenience
Cabin temperature is a good example: the setting one person finds pleasant feels stuffy or chilly to someone else, since clothing, sun through the glass and simple habit all pull in different directions.
Safety and Driver Assistance
Time spent stationary before setting off is the easy moment to locate wipers, lights and demisting. Searching for them later, in rain or fading light, is exactly the distraction worth removing in advance.
Multimedia and Connectivity
Battery level is the quiet constraint on a long drive, since a phone used for navigation drains steadily. If charging is available on board, topping up while underway matters more than how music or calls are handled.
