This article seems to be from a European / mild winters point of view, and mainly for people training?!
I live in Montreal and a winter bike is very much a thing. If not you have to prepare yours and spend much more time and money on maintenance.
And since lots of us here are using bikes through snow storms, slush, ice, salt, calcium, you can be assured that most of us will not use a fancy road bike for this.
I don't even use my hybrid in winter and have a cheap mountain bike just for this. But I must admit that I use it less and less, not because of disc brakes, but because we have a bike share system that is now working year-round. So sometimes I just rent a bike and don't have to bother with all the maintenance winter would be imposing on one of my own bikes.
Don't worry, car collisions are only one of the leading causes of preventable deaths in the US.
Who cares if you're blind, you need to go places. Here's your license. The other shiny dots are just NPCs.
Anything but public or active transit.
