Yes! Until that is written, however, anyone with a D700 can do
this. While you are crawling at 5 MPH or stopped in the backup,
just change your D700 MYCALL to "WRECK", and then for the next
"n" minutes, your radio will send out a WRECK OBJECT at that
location. Before you speed up again, then change your MYCALL
back to your MYCALL.
Meanwhile everyone in the region will see this WRECK object on
the front panel of their D700's and can see where it is and how
far away and even the SPEED of traffic past it (speed your car
was going at as you crawled up to it).
In fact, you can automate this by storing a permanent MYCALL of
WRECK in one of your PM's. Then you can switch between this
ALERTING object and routine driving with only two button clicks.
This is the kind of useful LOCAL info that APRS was designed to
display to mobile operators...

How does changing the station's MYCALL callsign create an object?
Isn't this just another station with the call "WRECK" ? <br>
<br>
This would never work in the L.A. metro area where there are an average
of 2-3 wrecks minimum on the freeway system at all times. (The local
area here, from a radio network standpoint, is about 80 miles across.)
If more than one is reported in the area you will have a single
symbol "hyper-jumping" all over the SoCal map if everyone uses the
same call. <br>
<br>
I suppose one could reduce (but not totally eliminate) the chance for
duplication by appending the route number to "WRECK" so that an
accident on the San Diego fwy (I-405) would be "WRECK405" while one on
the Santa Monica fwy (I-10) would be "WRECK10" .Since the route numbers
never have more than 3 digits, you can keep all variations within the
AX25 8 character limit for callsigns. <br>
