Even on the roads less traveled, it is highly probable that the front windows will be shielded from prying eyes.
The phrase, "my house is my castle", or whatever the real wording, has real meaning in England and I guess curtains/blinds are the last defence, since there are no longer protecting walls, save fences, or moats, portcullis or people to shoot arrows and dump hot oil on your head before you can ring the doorbell.
I might have to try windows on the continent - stay tuned.
