Not all cockwomblery is specifically prohibited, like nothing says I can't turn right out of my drive, but the acute angles of the road layout where it meets the main road to the right means I'd be either merging into oncoming traffic or making a U turn swinging across both lanes and possibly the cycleway opposite, even in my little car, so instead I turn left and make a U turn out of that end. If I went right and didn't reverse back along the 30m or so (or maybe far enough to turn in the road) once I realised the road layout, I'd expect to be open to an accusation of carelessness.
