Step daughter had an accident where the issue was a collision mid intersection, assumption of one party running a red light. No cameras, no witnesses except her and the other party, and both were adamant they had a green.
The car she was driving absolutely has telemetry that could have shown "was she at a complete stop, and for how long", immediately before the collision, i.e. showing being stopped at a red light before going (still some discussion on timing if jumping the gun, sure).
Insurance wasn't even remotely interested. It's not worth it to get that information unless, like I (and they) said, it's a very serious accident with a lot of money on the line and no other ways to determine fault.
