Well, it isn't quite as simple as that. On the 9th there's more room to the right than the left, and on the 10th missing right is definitely preferable to missing left (which is in the gorse) On the 12th again there is perhaps more room right than left.
In addition, even on some of the "obvious" holes with OB right it isn't quite so simple. For example, on the 14th driving left brings bunkers into play, and the drive has changed as the ball goes further. The longer the ball gets the more those bunkers come into play and the more room you have to the right. I rolled my drive past Benty in 2001, a bunker that few would have had to worry about even 10 years before that.
Clearly there are classic examples like the 16th and 17th where playing to the right gives a better angle but is risky to the point of foolhardiness.
And don't misunderestimate (sorry, I can't resist using that word sometimes) the possibility of missing left on some holes where you think you can't if you let yourself be lulled into a belief that there's an infinite amount of space to miss left. I well remember hitting a nice little duck hook over Cheape's on the 2nd on my last visit resulting in my playing an approach from the gravel walk that's along the edge of the property on the 17th hole. It'll give one a dose of humility to be forced to wait to play an approach to the second until after a group of seniors have hit their drives on 17 and walked by you wondering what kind of a crooked shot could possibly land you in that spot
The reason TOC works as well as it does is because when you look at it from a distance, you see some simple and apparent strategies. Then you take a step closer and see some exceptions to those strategies but think you have it all figured out now. Then you step closer and once again you discover new stuff. Its like a fractal, where no matter how close you get to it, new edges are constantly revealed.
