In my opinion this is wrong comparison. Simply because there is no physical obstacles that prevents you from doing what you have to do at your work, while in traffic there is plenty, hence the reason you're in traffic.
Such comparison alone distorts the view and paves the way to start to think that your minds lazy thoughts ("virtual obstacles") is actually something real, something you can't control.
In my personal experience, the moment you stop thinking about how hard it is to concentrate on a task and you start doing it, is the very moment when all those lazy thoughts disappears and you're back on empty "autobahn".
