Comfort and Convenience
People differ in how firm or soft they prefer the seat cushion to feel, and one passenger's idea of plush can be another's sense of being under-supported.
Safety and Driver Assistance
Practicing the reach and press of the main controls before setting off means attention can stay on the road rather than on learning switch positions mid-journey.
Multimedia and Connectivity
For phone calls, keeping a charging cable in a consistent spot means less fumbling when the battery is low, while saved playlists can be started without taking eyes off the road.
