Comfort and Convenience
Cabin temperature divides people more than almost anything else. One passenger wants airflow straight away on a warm morning while another prefers it gentle, and agreeing a setting is part of travelling together.
Safety and Driver Assistance
A few minutes before setting off, spent adjusting mirrors, checking which stalk does what and setting the route, means fewer things to work out later. Preparation in a quiet moment is simply easier than in traffic.
Multimedia and Connectivity
Hands-free calling is a practical matter of its own: if a system supports it, incoming calls can be answered without handling the phone, which matters most on routes with frequent stops and turns.
