An apt analogy, and I think your discussion of private roads / driveways is accurate as to what the problem is.

I will never forget being led from a highway, to a side road, to a gravel road, to a rougher gravel road, to a one lane gravel road, to something that looked like a washed out river at best, only to be blocked by a large steer standing in the middle of the "road" that appeared to be as stunned by my presence there as I was. I ended up having to reverse quite a bit before I could find somewhere to turn around. I deleted Google Maps shortly thereafter.
