Reporting the number of miles driven and the number of disengagements is required by law in CA. It is not voluntary. The reason some larger companies don't have reports is because they either didn't do autonomous testing in CA (many test in AZ) or that they do not consider their tests "autonomous" ( level 4 or above). This is the case for Tesla autopilot.
