His nick was radi6404 ... which I always found funny because it apparently was no mistyping, he meant it that way and used that nick on other platforms too, Isratrance for example.
I agree that some of his comments were - most harmlessly spoken - "kinda strange", but over the years I have developed a genuine like for his obsession with highways, mostly because I had to travel more around Austria in my (back then) new job and got to see a fair lot of these roads myself.
I have absolutely no clue what became of him, sadly
