Finally, such busses need to be smaller so that they fit within the design parameters of the existing road system. Otherwise, the growing number of such busses will exert constant pressures to build larger and larger roads, to the detriment of park values and visitor experience. As indicated earlier, the recommended plan fails to come to grips satisfactorily with the growth in the factors that stress the environment of Yosemite Valley. Limits are addressed only indirectly, with the question deferred for up to five years while the VERP process is pursued. This is particularly so with respect to growth in bus traffic.
Busses can bring far more visitors to the valley than can cars.
Total visitation via car is more easily limited by congestion and limited parking space. But if busses displace cars, the potential number of visitors is far greater. They can suddenly produce crowds that overwhelm special places. And as their numbers increase, so also will the pressures for more accommodations, facilities, and infrastructure. Once remote parking lots are built, it will be all too easy to expand them.
