Comfort and Convenience
Seating preferences differ mainly because people vary in height and leg length, so the same seat position rarely suits two drivers equally. Drivers usually settle on a posture that keeps pedals and wheel within easy reach.
Safety and Driver Assistance
Learning where lights, wipers and hazard switches sit before setting off means less searching later, since an unfamiliar layout draws attention away from the road at exactly the moment it is needed.
Multimedia and Connectivity
A phone that runs low on a long drive needs power, which is separate from playing music or taking calls. Where a socket or wireless link is available, each of those needs is handled differently.
