Comfort and Convenience
How warm the cabin should feel on a short winter trip differs between people. A passenger still in a coat may want cooler air than a driver who has been sitting still.
Safety and Driver Assistance
Before a night-time collection from a railway station, knowing how the interior light and door locks work is a small piece of preparation. It is about being ready before passengers arrive, rather than learning the cabin in the dark.
Multimedia and Connectivity
Waiting outside a sports club, many people want background music while they sit in the car. If audio playback is available, that need is simply passing the time until collection is over.
