Comfort and Convenience
Driving position is personal: height, reach and how upright someone sits depend on build and habit, so a setting that suits one driver can feel wrong to the next in the same car.
Safety and Driver Assistance
Before setting off, it helps to locate the basics, such as lights, wipers, mirrors and the hazard switch, while stationary. Preparation of that kind leaves fewer decisions for the moment they are actually needed.
Multimedia and Connectivity
Keeping a phone charged matters most when it doubles as the navigation screen. If a suitable power socket and cable route are available, plugging in at the start of a journey avoids running flat later.
