I live on Long Island, NY.

We use a nice mix of 30% salt and the rest sand.

Yeah our cars rust nicely and all turn white when we drive
in the winter (hint, its not the snow that makes the cars white)

I have a 92 sentra that has always been garaged. What I found
is that between the cars I own (altima and infiniti) the 92 sentra
which
was always garaged DOES show very little rust on it. The other cars
are newer and do have more corrosion on the undercarage.

Just my 2 cents.

The speed of corrosion is increased with temperature. The theory is you
drive in salty roads and then when garaged the vehicle is subjected to above
freezing temperatures and allows more corrosion.
When salt spray tests are performed the temperatures are elevated to promote
corrosion to speed up testing.
I do not know if being garaged will in fact be worse but I guess it could.
The fact is a warmer vehicle vs. a colder vehicle with the same corrosion
environment will corrode faster where it can.
