The rules are very simple - if you see a STOP sign on the road, you can not turn this face.

ps
it was not my idea, I just simplified it! A original idea by Javier Cabezuelo

1) Beltroad Cube




2) Crossroad Cube

Wow at first I thought you just had the idea but unless you are pretending really authenticly you actually made the mechanism.
The version III is mad. First cube where I would peel of the stickers. And mess up the configuration but hey.

Although the video shows that the mechanism is something different, the stop signs are equal to a bandaging between the cubie with the sign and the underlying cubie.
Inventive mechanisms but nothing new with respect to solving.

I stickered my puzzle and

And this is the original idea of Javier Cabezuelo, a good friend who asked me building this puzzle.
