That was basically one of my first reactions in my first hour of driving. »I can't possibly make a turn here. I don't see where I'm going.« That feeling fades over time and one (at least I still do with just a bit over two years of driving) adapts by going slower, looking more carefully, and especially looking for potential dangers before it's too late. Often (not always, as the article details) it's possibly to see ahead of time what can become problematic, e.g. overtaking a cyclist that you might have to yield to 100 meters later when making a turn. But it takes practice and I'm sure different driving instructors and different drivers place varying amounts of emphasis on such things.
