Comfort and Convenience
Comfort is personal before it is technical. Height, build and posture all shape where a driver wants to sit, so two people sharing the same car often settle on noticeably different seating positions and mirror angles.
Safety and Driver Assistance
The minutes before setting off are the easy time to locate hazard lights, the demister and the wiper stalk. Doing that while parked means fewer unfamiliar movements later, when the road is asking for attention instead.
Multimedia and Connectivity
On a long day of driving, a phone doing navigation duty drains quickly. Where a charging point is available in the cabin, it keeps the handset usable at the destination, separately from how calls or music reach the speakers.
