Today DH and I were towing a trailer behind his truck through town on a flat, smooth, divided four lane road, complete with center divider and generous bike lanes. Fucking bicyclist was cruising along a full foot outside the bike lane, which was clean, btw. Glass was the first thing I looked for when I saw him outside the bike lane. I rolled down the window and yelled that we were pulling a trailer and that if he valued his life, he'd get back in the bike lane, which he promptly did.
Being a jerk goes both ways. We had a saying in my hard-core cycling days. There's right and then there's dead right. Don't be the latter. If I hadn't yelled at him, our completely legal trailer, moving at or below the speed limit, might have squashed him like a bug. So happy it didn't, but WTF, bicyclist?
