Naples is the first place I got honked at for not cutting the person off. I was at a stop sign, making a left turn onto a main road that had a steady stream of traffic. Apparently, I was supposed to wait a few seconds and then just creep out, cutting cars off on the way, which is what I believe the driver on the main road meant when he beeped at me and gesticulated wildly while I was sitting still at the stop sign.
That city was the first place where I saw a guy traffic splitting with a car. It was an ancient topolino, but my jaw dropped as he was snaking through traffic like on a moped.
