Comfort and Convenience
Seat comfort tends to be personal, since body proportions and posture habits affect how supportive a given cushion feels over time.
Safety and Driver Assistance
Knowing where key switches sit before setting off reduces distraction, because simple actions like adjusting mirrors can then be done without looking away from the road.
Multimedia and Connectivity
A driver may want to keep a phone charged during short trips while still hearing directions clearly, so a stable mounting point and an accessible power socket prove useful.
