Here in town, there is a place where cyclists cross the oncoming lane to enter a bike pathway. The cyclists go downhill and thus have quite some speed. For the cyclists, they are catching a gap between cars. No big deal. From the perspective of a car driver, you have oncoming traffic in the same lane. Bonus point if the cyclist didn't signal their left-turn. I'm sure this location alone is producing a dozen of cyclist haters every day. I think the cyclists lack awareness that cars are bulky and heavy and thus require some free area ahead of them for breaking.
