I've run APRS with milliwatts on high altitude balloons, however those
have fantastic line-of-sight to "everywhere" so even if you're getting
less than 25% success rate to any given receiver, there's probably still
enough OTHER people receiving you, or heck 10% success rate will
probably still get at least ONE good position report to SOMEONE every 2
or 3 transmits.

For my own car use I've never needed more than about 5W, but I've
similarly never treated it like I need to get 100% of my packets
through. If you thought APRS was supposed to get through 100% of the
time, you probably don't understand APRS, nor the purpose of the AX25 UI
frame upon which it sits.
