Comfort and Convenience
Seating position is a personal preference rather than a fixed standard: height, leg length and the habit of sitting upright or reclined all shape what feels right, so two people rarely settle on the same setup.
Safety and Driver Assistance
Working out where the main controls sit while stationary is simply easier than doing it in moving traffic. A few minutes spent locating lights, wipers and demisting before setting off keeps those tasks routine later.
Multimedia and Connectivity
Battery level is the plainest need on a long trip, since a phone used for navigation drains steadily. A charging arrangement that works from the driver's seat is worth sorting before departure rather than mid-route.
