> How would you alternatively design a system that calls emergency services in a crash? If significant motion does not stop shortly after a candidate crash is identified then reject the candidate as a false positive. Maybe also listen for voices. If you can detect people talking and they seem to be reasonably coherent that suggests that even if there was a crash there are people on site already who can take care of summoning emergency services if needed.
