Comfort and Convenience
Seating position is a personal matter: height, leg length and the habit of sitting upright or laid back all pull in different directions. Two people sharing one car often settle on noticeably different settings.
Safety and Driver Assistance
Before the first drive it is worth finding the wipers, lights and mirror adjusters while stationary. Rain or dusk arrives without warning on a commute, and preparation means one less thing to search for then.
Multimedia and Connectivity
Keeping a phone charged on the move is its own need, separate from playing music or taking a call. A commuter who arrives with a full battery can leave the car without hunting for a socket.
