I also think that a trailhead tag is needed.

I don't believe that implicitly determining trailheads will work.  A
trailhead is more than where a trail crosses a road; it's a 
significant place to access a trail in the eyes of the hiking community,
typically (but not always) with parking and typically (but not always!)
a sign of some sort.

Something as simple as trailhead=yes could be useful, placed on either
an area way around parking, sign, and beginnings of trails, or on a node
of a trail (that's not a node of a highway).  A place with parking and 2
trails should have only one trailhead object.

Or maybe trailhead doesn't need to be connected to the hiking ways, and
it can just be a point in the general area one would stand in to follow
the instructions "meet me at the trailhead".
