Hi, I looked at all those locations in Google Maps and the problem is there isn't continuous Streetview coverage at them. The last one has a single Streetview image, rather than continuous road coverage.
There is road coverage near those locations but you have to zoom out in Google Maps and click the "yellow man icon" to bottom right of map window to see the blue lines that represent road sections that have Streetview. Single Streetview images are shown with little blue circles, but aren't connected in a way Explorer can ride through them.
See the red areas I marked in the picture below
