Comfort and Convenience
Seating position is a good example. Height, leg length and the way someone likes to hold the wheel all differ, so a driving posture that suits one person can feel wrong to another.
Safety and Driver Assistance
Setting mirrors, seat and lights before moving off is worth a moment of standing time. Sorting these while parked means fewer adjustments later, when attention is better spent on the road ahead.
Multimedia and Connectivity
Keeping a phone charged on a long day matters if it is also the navigation device, since a flat battery ends the route guidance. Where charging is available, a cable that reaches comfortably helps.
