Comfort and Convenience
Tolerance for bright light varies widely; one passenger reaches for sunglasses while another simply lowers a visor. Eyesight, seating position and the direction of travel differ, which is why no single arrangement suits everyone aboard.
Safety and Driver Assistance
Familiarity costs nothing and pays off in awkward moments. Knowing by feel where the demister, horn and headlight controls sit means attention stays on the road rather than on the dashboard.
Multimedia and Connectivity
Calls on the move are the awkward part of any long trip. Where a hands-free function is available, answering without handling the phone keeps conversation from competing with driving; otherwise, a stop is the sensible option.
