If an On-Star device, would be true two way, with GPS tracking, with

There already exists a somewhat similar system to broadcast weather
alerts to a passive receiver, although not normally deployed in cars.
Boaters already can have a Digital Selective Calling VHF radio in
their boats by which a coast guard can issue warnings. Such a system
is being mandated in the UK by a phase in process (e.g. new radios
with the old paradigm cannot be marketed unless they have DSC.)

And horror of horrors, one could alway investigate Broadband over
Powerlines (BPL). Wouldn't that give us hams some gas.

The issue of installing a proprietary receiving device inside automobiles,
mandated by federal action, is one that is being given serious
conversation. The one problem that appears to be an issue is the liability
one. It will be a matter of time that someone will sue saying that the
system scared them or distracted them and caused this or tat accident.
