Comfort and Convenience
A preference for cushioning firmness depends on body build and personal sensitivity, so the same seat can feel supportive to one person and too hard to another.
Safety and Driver Assistance
Knowing the location and feel of the main controls before setting off reduces distraction, as a driver can adjust temperature or wipers by touch rather than looking down.
Multimedia and Connectivity
A phone may need charging during a long drive, and if the cabin offers a power source, a suitable cable keeps the battery topped up for navigation or communication.
