I think the HamHUD firmware has a DigiMeter that lets you know how
well you're getting digipeated, which may not be all that accurate
depending on how much local RF noise floor you have in your vehicle.

It might even be cool to have something like this:  If the DigiMeter
is low, and you're not receiving many packets at all, throw in an
extra posit some short time period after successfully decoding a
packet.  Of course it'd require a random short period, plus a
dead-time in-between such so that we wouldn't get LOTS of packets by
lots of stations all at once.

Somebody will probably shoot holes all through this idea, but just
throwing it out there.
