Comfort and Convenience
What feels supportive to one person can feel too firm to another, so being able to fine-tune the seat position matters more as the hours pass.
Safety and Driver Assistance
Being able to operate lights, wipers and demisters without searching for them means less distraction, especially when weather changes quickly on a long route.
Multimedia and Connectivity
A passenger may want to charge a phone while a driver listens to navigation prompts, so separate power outlets and straightforward volume controls keep these needs from competing.
