I did a trip through a bunch of national parks recently, and was thinking why the hell isn't there some sort of organised transit - be it shuttle busses, or trains for the capacity. The amount of space wasted for parking in a nature preserve was crazy, not to mention all the infrastructure for the traffic jams.

Then went to Grand Canyon and Zion and saw they have shuttles which are sometimes exclusive (if the shuttle is operating you cannot take the road), which makes so much more sense, and even allows for more flexibility (you can go on a hike which is out, and not have to walk back the same way but hop on the shuttle bus).

I don't know why it isn't more common, especially when most parks have a relatively short main road/loop that 90% of visitors never leave. Yosemite for example has a great bus system that goes everywhere you need, except that they don't block private cars so the buses constantly get stuck in traffic. I think the exclusive shuttles at Zion are relatively new, so maybe it will spread to more parks in the future.
