National parks are great opportunity for sharing rides, rail, or bus. I think Yosemite valley should be 100% free from personal vehicles. I’m talking about climbing a mountain and starting at the trailhead at 6am. Mountain biking or paddle boarding or surfing. Going fishing or hunting in a place nobody else goes. Maybe you’ve never experienced real solitude, but ridesharing and transit isn’t going to get those experiences. There is not a future free from personal transportation. Even in a post apocalypse anarchy, people will build off grid solutions to drive electric ATVs and bikes and buggies and whatever else.
