Here is a part of my commute. It's a suburban road (speed limit is 40), 2 lanes each direction with light-to-medium traffic. (Note: this is just a picture from Google, not my actual picture so ignore the pickup that's there.)
I have been honked at the last two times I've been in this spot. I've been experimenting with different lane positions; yesterday I was riding in the right lane, about 3 feet from the right curb. I know this is an age-old question on this forum, but I came up with some specific options for why this idiot honked. I thought it might be interesting to post a poll. What do you think?
