There's a difference between being around a little salt water, and driving down a road that's WHITE with salt, with the occasional 2" tall speed bumps, where the trucks stop but continue to dump salt on the road.
As you ride along on this salty surface, a cloud of salt is raised and the entire undercarriage is in a constant cloud, with this salt powder getting into every last crack and crevice. What's worse, is they now spread beet juice/salt slurry on the roads that does the same, splashing into everything. Hot, soapy water will wash it out, but when your garden hose spigot is outside, under 2' of snow and it's 12 degrees F, washing isn't an option.
Again, everyone is welcome to do what they wish.. I'm waiting until spring to get my bikes out.. I can barely see through the windshield of my car because of salt spray, needing to clean it every 5 minutes while driving in certain areas.. I don't want to ride in that crap, and I don't want my motorcycles/scooters in it either.
Beet juice/Salt slurry application. (it doesn't dry)
Car salt (not my vehicle, but typical)
And that's the back of the vehicle. Imagine what the front and areas around the tire look like!:)
OK, here's what it looks like.. I don't want this on my bike..
