I definitely agree.
While the majority of bicyclists are okay, the percentage of louts with utter disregard for fellow road-users is much higher than it should be, unfortunately.
From what I have seen so far around here, the louts are from urban areas and think they can do whatever they want out in the country. They take over the road and know that if you hit them, you are to blame, no matter what. They’ll turn without arm signaling, stop dead to gawk at a deer, and throw their garbage on the side of the road, which often times is my front lawn.
