1.) It isn't the noise made by the actual contact of particle to the
antenna that makes what is commonly called p-static noise.

Assuming that "p-static" is precipitation static, you already
agreed with the laws of physics that make your statement false.
Any particle with a charge different from the antenna wire
will cause particle noise even when the corona threshold
is not even close. There's no way to stop a charged particle
from transferring its charge to a bare-wire antenna. There's
no way to keep that charge from equalizing through the
link coupling in a non-folded dipole. This is all easily proved
using very small charges nowhere near the corona threshold.

I agree that some cars are white. I just disagree with your
assertion that all cars are white. I agree with the 2000
ARRL Handbook about precipitation static Vs corona static.

The 2000 ARRL Handbook says:
"Precipitation static is an almost continuous hash-type noise
that often accompanies various kinds of precipitation, including
snowfall. Precipitation static is caused by rain drops, snowflakes
or even wind-blown dust, transferring a small electrical charge
on contact with an antenna."

I also agree with what they say about corona static which certainly
exists and is what you are talking about. But corona static is not
the only thing that exists, as you are asserting.
