Comfort and Convenience
Cabin temperature divides passengers more than almost anything else. One person finds a setting pleasant while another beside them feels it is too cool, so agreeing on a compromise early is normal.
Safety and Driver Assistance
Adjustments belong to the moment before setting off. Mirrors, seat and steering position are quick to set while stationary, and anyone driving a borrowed or newly bought vehicle benefits from that pause.
Multimedia and Connectivity
Calls arriving mid-journey are the awkward case. Where hands-free telephony is available, answering without picking up the handset is the practical point; where it is not, letting the call wait remains sensible.
