Stretch Hummers.. in Roma?

Normally, I'm used to seeing mopeds and Smart cars all throughout Rome. There just really isn't room for cars bigger than that size. For example, when I see a minivan here, it's weird. At home, it would be equally as weird to see some one driving a Smart car down the highway. However, I saw the biggest car I have ever seen in Rome since I've been here (besides the double-decker tour buses.) Last weekend, after Rome won the World Cup, I saw a stretch Hummer drive by on the road in front of my apartment! There were people hanging out of the sunroof and the windows jamming out to music that I think was rap. They were videotaping everything going on around them, and seemed to be pretty intoxicated. I really couldn't tell if they were Italian, or some other nationality. Regardless, to be driving a stretch Hummer down a crowded highway full of cars that are about 1/10 the size of your own is pretty intense!
