Comfort and Convenience
Some travellers like the cabin bright and the conversation going, while others prefer a quieter, more private atmosphere. That split is ordinary and is best settled by asking rather than assuming one arrangement suits everyone.
Safety and Driver Assistance
It is worth learning how the windows, mirrors and door locks work before leaving, especially if the first stop is an unfamiliar car park after dark. That is preparation so a driver is not guessing under time pressure.
Multimedia and Connectivity
A passenger may want their own music while the driver keeps a phone free for a later call. If playback is offered, it can cover listening; charging the handset is a separate task.
