Comfort and Convenience
Comfort is personal: one driver sits upright and close, another further back with arms extended. Height, build and habit all feed into that choice, which is why a position that suits one person can feel wrong to the next.
Safety and Driver Assistance
Learning where the basic controls sit, from lights and wipers to demist and hazard switch, is best done while parked. Sorting that out beforehand means an unexpected shower does not become something to hunt for mid-journey.
Multimedia and Connectivity
Phone charging is the plainest need: a battery that starts the day full rarely ends it that way after navigation. Where a charging point is available, keeping a cable in the car removes the question entirely.
