Comfort and Convenience
Seating position is personal. One driver prefers to sit high and upright for a clear view down the road, another lower and more reclined, and neither choice is generally right, since height, build and habit differ.
Safety and Driver Assistance
Setting mirrors, lights, wipers and climate before moving off is simply preparation. Done while stationary, those adjustments are not competing for attention later, when the first busy junction or a sudden shower arrives.
Multimedia and Connectivity
Phone battery is the plain concern across a day of errands. Where a charging option exists, topping up during a drive means the device is still usable on arrival; calls and audio playback are separate functions.
