Comfort and Convenience
Seating position is a personal preference. Height, reach and the angle people like to view the road from all vary, so a setting that suits one driver can feel wrong to the next sharing the same car.
Safety and Driver Assistance
Preparation is simple: before setting off, it is worth locating lights, wipers, demisting and hazard switches while stationary. Doing that calmly in a parked car means one less thing to work out later.
Multimedia and Connectivity
Keeping a phone charged on a long day is its own need, separate from calls or music. If a suitable socket or port is within reach, the practical value is arriving with a usable battery.
