Here it still is a problem and we have to get additional corrosion treatment. The usually reliable undercarriage parts like brake lines, fuel lines, gas tanks suffer and last fewer than than 10 years.
Most people forego rust prevention treatments because they never plan on using their vehicles more than 5 years. That creates serious failure danger from older vehicles on the roads.

I agree. City engineers here don't bother with thermometers. Spread, spread, spread!
When I was a kid, there was no salt spreading, they used coarse sands. but not any more.
