Comfort and Convenience
Seating position is the usual starting point, and preferences differ because body proportions, leg length and arm reach are not the same for everyone. A comfortable posture for one person can feel cramped for another.
Safety and Driver Assistance
Spending a few minutes with lights, wipers, mirrors and climate controls while parked means you are not searching for them later. Preparation of this kind simply removes small distractions from the start of a journey.
Multimedia and Connectivity
Keeping a phone charged during longer trips matters to many drivers, and where any charging point sits determines whether a cable stretches awkwardly across the cabin. Calls and music are separate questions entirely.
