Comfort and Convenience
Some travellers prefer an upright posture, others sit further back with arms extended. Preference here follows height, leg length and simple habit, so two drivers rarely agree on the same arrangement.
Safety and Driver Assistance
A few minutes reviewing the owner's handbook and trying each stalk and switch turns unfamiliar functions into routine ones. That preparation belongs before departure, not at the first roundabout in the rain.
Multimedia and Connectivity
Calls on the move are the awkward part of a long trip, since answering by hand is both illegal in many places and distracting. If hands-free functions are present, they cover that need specifically, separately from charging or audio playback.
