Comfort and Convenience
Seating position is a personal matter. Height, arm reach and preferred posture vary from one person to the next, so an arrangement that suits one regular driver can feel wrong to another sharing the same car.
Safety and Driver Assistance
A short pause before setting off is worth the time. Finding the lights, wipers and hazard switch while stationary means they are already known when needed, rather than something to hunt for mid-journey.
Multimedia and Connectivity
Keeping a phone charged across a long drive is a practical concern in its own right, separate from calls or music. Where a suitable power source is available, a cable keeps the battery topped up en route.
