Your road-rage claim is bogus.
I couldn’t follow the description events well. Dunno if it was the writer or my comprehension, but if I gather it correctly, the cars ahead might have been going slow because of the cyclists. This happened to me once, feeling impatient behind a car doing well below the speed limit and not seeing cyclists ahead due to a gentler curve in the road, so I went left to pass and saw the cyclists when I did, then backed off. I realized what I did wrong and ever since them I try to be more cognizant of why a driver might be going slow before I make any decisions.
I would classify passing on the right as "road rage", in most instances.
Many States, counties and/or cities say to give 3 or 6 feet of clearance when passing cyclists. On a 2 lane road that means you’ve got to get into the on-coming lane especially if cyclist’s are traveling side by side. Mixing bicycles and motor vehicles on a well traveled road after dark is a tort lawyers dream.
