The meme doesn’t really reflect reality, it’s just a weirdly remixed right-wing meme. Climate change denialists don’t ask for sources as they dislike them in general (Youtube videos and huffing your own farts is quite enough for them), they will just say the MSM has implanted the snow propaganda into your brain.
The video is half an hour long and I really don’t feel like watching it all to find out something that could be said in one or two paragraphs of text, so I ignored it at first. As I expected, the video deals with a bunch of more or less relevant topics that you or OP didn’t mention at all. It actually is a bit interesting, I’ve watched a part of it, and I do have to admit that US fire trucks are bigger than those where I live. The problem is that their deadliness is a consequence of several other factors, and only indirectly of their size. What you and OP decided not to do is to communicate that point with any nuance, and all that I could read from your comments is that, by some logic, getting hit by a 10-metre truck is much safer than getting hit by a 15-metre truck. OP complained about the driver “right-hooking” the cyclist, you just said the trucks are too big, do I really have to watch a half an hour video to understand why your comments don’t sound nonsensical?
