The mountains in the background arent Eiger, Münch and Jungfrau (the mountains directly at the Eiger Nordwand track), so lets say your driving up the first, blocked road left, before the hairpins come, then left into a tunnel, up and further away from the track, its possible that you can see a lot of different mountains. It always depends on how they placed the cameras for that video.
Although, i dont state that as a fact, but in my opinion its extremely possible.
1 location: Eiger or Swiss Alps with that mountain road, the Eiger Nordwand track and Swiss Alps Rallye?
Sounds logical and possible to me...
