Comfort and Convenience
Seating position is a personal matter. Some drivers want to sit high for a clear view of the road ahead, others prefer lower and more enclosed, and height, build and long habit pull that choice differently.
Safety and Driver Assistance
A few minutes spent stationary locating the hazard switch, the demister and the wiper settings means less searching once the car is moving. Preparation here is simply about knowing where things are beforehand.
Multimedia and Connectivity
Keeping a phone charged is its own need, separate from taking calls or playing music. On a commute of fairly fixed length, whether the battery finishes higher or lower than it started is what gets noticed.
