I started to leave this alone, but I believe it should be addressed.
Hard as it is for the male ego to accept, there are different levels of skill and experience, especially in winter conditions. Conditions that make you tense are another day at work to a driver who spends much more time driving in winter conditions than you do. I'm firmly of the opinion that if you're so tense and moving slow enough compared to traffic that you feel the need to run your flashers, you need to park and stop being a rolling road hazard. All running flashers does is scare and confuse the 4 wheelers, who have a tough enough time not being idiots around trucks as it is. One slow truck on a busier highway can screw up traffic for a half mile or more. Besides all that, you're not a hall monitor who gets to decide what the safe speed should be.
And because this always degenerates into a peeing contest, the last 20 of my 35 years has been running a high percentage of my miles in the northern winters. And since my only incident was 30 years ago (and involved a naked wife on the doghouse) and 3 million plus miles ago, my record allows me to be the arrogant prick who can scold you for how you're doing things. Wake up and realize that while some of the faster guys are idiots (and they're not hard to spot) some of them just have a better skillset. It's not easy to swallow, but it's true for all of us.
"Everyone faster is a lunatic, everyone slower needs to learn to drive." It's a trope that is common among all drivers, car and truck alike . Wisdom is understanding why that's a falsehood.
