Its not the "vehicle or Radio type" at all that is of interest.
It’s the *application*, or what is happening in the surrounding
local area...

I think some people are missing the point.  This SSID discussion
is about the advantages of what a MOBILE can see on the front
panel of his radio or on his attached GPS map.  

With maybe a dozen callsigns flashing on the screen a minute, we
usually want to ignore most of them, but also have a way to
notice if there is one that we might have further interest in. 

If we see a -11, we might get excited!  It might be a balloon
event worth chasing, or an aircraft worth digiepating through or
contacting if he includes his frequency.

If we see a -6, we might take a closer look to see if it is a
special event or activity going on, or a special test or

If it is a -10, it might be the local Igate, and it would be
nice to check it out to see if it is 2-way or not.

If we see a -9, then it might be a nearby mobile.  This usually
means a real-live human ham, who might want to QSO...

If we see a -7, it might be someone doing something special with
his HT.  Generally, people do not always carry their APRS HT on
a routine basis, so when they do, then they are often up to
something we might be intereseted in ...

If we are wondering about the weather and see a -13, we might
want to check it out to see the WX up ahead of where we are

If we see a -8, then it might be someone on a boat or RV out
playing, or is up to something interesting.

So, seeing the callsign and SSID flash by gives a hint as to
whet that station might be doing and whether we want to take the
trouble to go check it out on the other screens.

So it is not about particular stations or hardware so much as a
first-order clue as to what that station might be up to.
