We have been living well with one vehicle and I have considered getting a scooter or motorcycle to get to trailheads so I don't tie the car up. I've assumed that I would chain it up at a trailhead to thwart thieves, but there is still the possibility of vandalism. That is a possibility with cars too.
That aside, I have done some research on taking buses to trailheads. In Washington state, AMTRAK provides bus service to some of the mountain pass summits that are also crossing points for the PCT. There are some other local mass transit bus options too.
Some bus options allow using a bicycle as well. That opens up riding a bike to a trailhead. It should be easy enough to stash a bike in the brush and cable or chain it to a tree.
The other hybrid travel option is built around a number of roads that have been closed to vehicle traffic due to flood damage. Most can be accessed with a bike, reducing hours of walking to the original trailheads to fractions of an hour by bike.
I've had a pet progeny in mind for years involving a ski and hiking train loop through the Cascades. This is something that has been done in Europe for decades. A light rail system paralleling the major highways could link the major ski slopes in the winter and drop hikers off at trailheads in the summer. I would expect that all kinds of service industries would develop around the transpotaton hubs.
The core concept is that we are still stuck in a frontier/pioneer frame of mind when it comes to backcountry access. We are living on another planet now and it's time to rethink these things. Of course it inclines so much more, like urban planning, suburban sprawl and more.
