If i should wave or flash my lights everytime i meet another MB, i would look like a retard flabbing my arms around all the time and continuesly flashing my lights. I would get arrested!
I live in Denmark. And we have imported, (most from Germany), used MB's ALL over the place.
But when driving my Miata, i do wave and pop the pop-up headlights when i meet a fellow Miata driver. (Miata's are pretty rare around here, unlike MB's)
