Comfort and Convenience
Preferred seating position is a good example: some drivers like sitting upright and high for a clear view forward, others lower and more reclined. Height, build and long-standing habit all pull the preference in different directions.
Safety and Driver Assistance
Learning where the main controls sit before setting off is simply sensible preparation: lights, wipers and demisting are easier to find when they have been located once while stationary rather than hunted for mid-journey.
Multimedia and Connectivity
Keeping a phone charged on longer trips is a practical concern in its own right, separate from playing music or taking calls. Where a suitable power outlet or cable is available, navigation can run without draining the battery.
