I have never actually done the cross my self, but I can see why it would be creepy. Cars in the left obscure any cyclists that may be about, as a result cars in the right dont see thus just proceed to over take as normal, which doesnt give the cars on the left any room to move over safely to pass the rider. They have that walk way up the middle, but it is not designed to ride in and it is a fairly narrow bridge so there is no real way of providing a curb for the riders either.
