Comfort and Convenience
Seating position is a personal matter. Some drivers want to sit high for a clear view over the road, others lower and more reclined, and body proportions and long habit push each person toward a different settled posture.
Safety and Driver Assistance
Spending a few minutes stationary with the lights, wipers, mirrors and demisting controls means they can later be found without hunting for them. Preparation of this kind belongs at the kerb, not in moving traffic.
Multimedia and Connectivity
Keeping a phone charged across the day is its own need, separate from calls or music. If a suitable power outlet and cable are available, the commute itself can top the battery up.
