Comfort and Convenience
Comfort preferences differ mainly because bodies do: a seating position that suits a tall driver can leave a shorter one stretching towards the pedals, so the same setting rarely feels right for everyone.
Safety and Driver Assistance
Learning where the lights, wipers and demister controls sit is easiest while parked, since hunting for an unfamiliar switch in traffic means time spent looking at the cabin rather than the road.
Multimedia and Connectivity
Charging, calls and music are separate needs: a cable that keeps a phone topped up does not always carry audio, and hands-free calling depends on its own connection rather than the charging lead.
