Ditto MJ.
Most of those pictures are all pretty typical Scottish weather, none of which would have caused any issues flying VFR. In all cases you could still see the horizon through the showers, only in the last one would I have made a slight deviation to zig zag around them.
It was the statements I found werent that realistic as I would be considering numerous factors in any such decision rather than just one. Before scudding low over the top of a hill I'd want to make sure I had an idea of the local wind direction and strength, a report of light turbulence from another pilot tells me very little..... If I know how strong the wind is and where its coming from I can figure out the safest way to cross the hills low level myself, if at all.
Much better effort than the last one of these I saw however.
