For about a kilometre this afternoon I was in front of a recent 911 in flat black and behind a dark red Super Beetle, in pretty good shape with chrome wheels and what looked like some kind of non-standard alignment (not that I'm an ACVW guru.)
"Herr Dr. Ing. Porsche, come on down: this is your life!!"
Sounds like you interrupted a cruise . . . and became "that guy" 
Now that you mention it, it does sound like that, but nope: the VW was already on the highway; the 911 came on right behind me and left two exits later, while the VW kept chugging along. They may not actually have even seen each other around my MPV.
