No mate I don’t know him, but on the subject of distance around..
The 6 k thing is an urban myth perpetuated by some. If you consider the road around Oz to be a circle you can see the following.
It’s about 6 times further around a circle (diameter) than it is from the centre of that circle to the edge (radius).
Now if you consider that the centre of the outside lane is say, 6 metres further away from the centre (an increase in the radius by 6 m) then the budding Pythagoreans will realise that it’s an increase of about 36 m on the outside lane mathematically speaking.
Now of course it’s NOT a circle, but the thousands of left and right bends will approximate to being equal and the effect will be the same.
I once saw Professor Julius Sumner Miller pose the question…
“If I wrap a ribbon around the equator of the Earth an pull it snugly tight and tie it there.
Then I cut the ribbon and add one foot to the length, how high will the ribbon then sit from the surface…?
The answer..?
2 inches…(because 6 x 2 = 12)
Back to the topic of our Guzzi guy.
I saw this in Beaufort (Australia) some time ago

Obviously a bit ratty, but well travelled and I sort of really liked it..
Slightly reminiscent I’d suggest.
