No wonder I never hear anyone on Voice ALert. With a combined meeting speed of 120 MPH, that is a possible distance of almost 16 miles between beacons of two hams going opposite directions, far beyond simplex range.
That is why I like Proportional pathing. It still gives me a local simplex beacon once a minute to have a good chance of hearing or being heard by a meeting interestate situation within a mile of each other, while still resulting in only 1 packet ever 4 minutes via WIDE2-2.
I think smart beaconing really shines when doing special events where you want a smooth track of the event..
