David,
Over time golfers seem to find the shortest route, particularly those on foot.
Is it just a case of not enough time for the narrow 'goat' like tracks between tee and fairway?
E.g. I noticed at Sand Hills that there was always a thin little track for those carrying their own bags, but they were not always obvious, and were often quite different to the paths. The same applied off the back of most greens to tees as well, although knowing where each tee was, was more difficult for a first timer.
So, David, do you think that is the reason the lack of tracks?
I agree with you, that continued separation from the routing of the each hole, from tee to fairway or from fairway to green, is undesirable and does in no way enhance the experience. This to me is at the heart of the main issue of riding in a cart.
