When I worked in car insurance, besides our own telemetry, we got at least

- Willis Towers Watson (WTW) aggregated driving data

- Verisk (afaik this was mostly around vehicles, not people)

- Various reports directly from state governments

- LexisNexus (multiple different report types)

Really any mobile app that has accelerometer or gyroscope access (even without GPS) can estimate driving safety. Using phone movement and angle, you can estimate driver vs passenger.

Cambridge Mobile sells equipment a lot of insurers use and afaik also data

The magic keyword to look for is "telematics"
