Comfort and Convenience
Noise tolerance varies widely. One passenger reads happily with conversation and music around them, while another wants quiet after an hour; the difference is habit and hearing, not the distance travelled.
Safety and Driver Assistance
Drivers new to a particular car benefit from sitting still for a moment and working through the switchgear, including how mirrors and lights are operated. Preparation while stationary leaves attention free for traffic later.
Multimedia and Connectivity
Calls on the move are the awkward part of a long trip. Where a hands-free function exists, setting it up before departure is sensible; music and charging are separate matters, handled by their own settings and cables.
