Why would you need SPOT? *If ADS-B is providing real time position

ATC data.

Coverage - will ADS-B find me when I'm down in some valley who know
where.

Signaling - How do I tell via ADS-B the pilot wants a retrieve is OK
or in distress?

It is not clear that people really want to be tracked by the feds and
there is still that whole unresolved anonymous VFR issue (or has that
been settled?)

I see SPOT as an improved ELT, and ADS-B as an improved TCAS/TPAS.
Different uses, but they do overlap.
