A reflection of our world population problem really. Everyone wants to be there but the place just can't handle it in its current design. Bringing more people there by conventional means is going to further destroy what people are coming to see, natures beauty. Building more and bigger roads is a terrible idea. If we want to increase capacity then we need to scrap current logistical systems and rehtink the whole plan. We would have to incorporate more public transit and treat the place more like a delicate amusement park. IE, leave your polluting, traffic causing cars outside the park and enjoy the sites by energy efficient busses, vans, bikes, or your own two feet. A pipe dream I know but I just can't stomach the thought of building more and bigger roads into the heart of one of the most beautiful spots on earth simply for profit.. Because that's really the motive behind it all in my opinion.
