Surprisingly difficult to do. The assumption is that there are some things we do in our life that act as a blank space that must be filled with something. Productivity, or deep thought, or whatever. People go through life always doing something so there's never a "wasted" moment, but I'd argue thats a recipe for burnout and unhappiness.
There's a buddhist concept of suchness, seeing things exactly as they are in the present without judging them or trying to change them. Doing anything else but "just driving" is trying to live somewhere other than where you actually are. Where ever you are, and whatever you are doing right now is what life is, your life isn't somewhere else in the future, and you don't need to escape from a mundane task and rush somewhere else to experience life. All of it is life, even the boring parts.
