Comfort and Convenience
Where one driver wants to sit low and reclined, another prefers an upright position with a clear view over the bonnet. Build, height and habit differ, so a comfortable setting is personal rather than universal.
Safety and Driver Assistance
Sorting out mirrors, lights, wipers and demisting before setting off means those things are already handled when the road demands attention. A few seconds while stationary are easier to spare than while moving.
Multimedia and Connectivity
A phone that leaves home part-charged should not arrive at work empty, so where a power source is available in the cabin, the commute itself can cover the topping-up.
