I've spliced together the back projection in the episode in the correct order. No sign of this at World Backgrounds, so I suspect that this could have been shot for another film project.
Don't be fooled by the english signs, I'm sure this is in the alps.
Slow-mowing the bit where Prisoner drives past the pink wall, highlighted as the "still" on your vid, with the blue parasols, reveals the words, "RESTAURANT" and "TEA ROOM" and what looks like "CAFE" and possibly "BEERS", so I suspect that particular bit is in England someplace.
This is no help either...

but does show a genuine Austrian Gasthof.... at 5:18 precisely

A lot of it does seem to be up on YouTube - I've just watched some of it posted by 'LorreB' which has quite a bit of back projection.
