I don't care for being passed on the right. On my commute home, I am lucky to have a nice wide road that I ride. The problem is when it is time for me to make a left turn. I turn on a side street, so no traffic light or anything. I move from the right side of the road to the left to make my turn. If there is traffic coming the other way that makes me come to a stop, then the cars behind me like to pass very close to the right of me.
I get more close passes on this turn then anywhere else on my commute. Since the road is wide, they don't slow down a bit. I also guess since I am now on the side of driver, the driver can easily tell that he is not going to hit me, so they pass closer. At least that is my guess as why they pass so closely.
