Comfort and Convenience
Cabin temperature is a good example of how personal comfort is: one person sets the vents low and warm, another wants cool air on a short run. Preferences differ by clothing, time of day and simple habit.
Safety and Driver Assistance
Learning where the lights, wipers and hazard switch sit is best done while parked, not mid-junction. A few minutes of preparation before setting off means an unexpected downpour or dusk arrival calls for recall rather than searching.
Multimedia and Connectivity
Charging is the commuter's recurring need: a phone that leaves home part-full should arrive usable. Where a suitable power source and cable are to hand, topping up during the drive keeps the evening return from starting on low battery.
