alt Hacker NewsWatch the channel Auto Parts City on YouTube, I assure you it is not overblown. It's a junkyard owner. A ton of cars come through there that run fine and could otherwise be very serviceable, but the frame/body are crumbling from rust, so they have to be crushed. We're talking cars that are 10 years old. And yes, it even includes Toyotas and Hondas. (In fact they're more likely to end up crushed for that reason than another car is, since a Nissan or Hyundai's transmission and engine won't last long enough for rust to really end its life.)
From a certain perspective, maybe some people don't care if they would be getting rid of the car in like 5 years, but if you do want to keep a car 15 years and you live in "salt country" I would strongly suggest doing something about the salt regularly.
Selection bias. Cars that were not treated for salt, and didn't die, didn't end up in the junkyard for stories to be told.
My first car spent its first 15 years in the Midwest. No garage. Very irregular car washes (perhaps once a year when I owned it). It lasted about 20 years total. When I lived there, I didn't know anyone who had to give up a car due to rust. There definitely was rust, but not something that caused the car to break down.
