Making it a hassle to drive a car in Yosemite means letting the green bigots regiment visitors in buses. Instead of going where you want to go, when you want to go there, you will go where the park bureaucracy wants to take you.
When you are in your own car, you can stop and get out to walk around when you see something you like, or just go to the bathroom when you need to. When you are regimented in buses, you can go only when and where the bus schedule permits. For young children and the elderly especially, this can turn what could be an enjoyable experience into needless stress.
The last thing you can expect to learn from most media accounts of the activities of green bigots is an account of other people's objections to their power grabs.
Instead, there is a whole vocabulary of misleading words used to paper over and sugar coat the plain fact that green bigots feel entitled to impose their vision at the cost of other people's rights. Thus it is called a "renaissance" to lose your right to choose what you want to do in Yosemite.
There is never a lack of excuses when people want to boss other people around. There are lots of vague and lofty words about a "fragile" or "sensitive" environment -- but ask the green bigots for concrete criteria by which we can determine whether a particular environment is or is not "fragile" or "sensitive."
Then ask for hard evidence. You are not likely to get any.
The story about the "renaissance" in Yosemite speaks of the new changes as having "restored" the Merced River. I have watched the Merced River flowing and cascading through Yosemite for more than 20 years without seeing anything that needed to be "restored."
Maybe honesty needs to be restored.
