The requirement does not seem to be there for driver-assist vehicles. Also, it's a state-level requirement. Looks like it's just in CA for now. The accidents detailed in the Google reports are all from California.

And, Tesla may be unwilling to start reporting driver-assist accident rates to the public unless the other driver-assist car companies are forced to do it too.

I'll make an addendum to my above comment.

> The accidents detailed in the Google reports are all from California.

You could have opened the first report[1] on that page and notice this is wrong.

> June 6, 2016:​ A Google prototype autonomous vehicle (Google AV) was traveling southbound on Berkman Dr. in Austin, TX in autonomous mode and was involved in a minor collision north of E 51st St. The other vehicle was approaching the Google AV from behind in an adjacent right turn-only lane. The other vehicle then crossed into the lane occupied by the Google AV and made slight contact with the side of our vehicle. The Google AV sustained a small scrape to the front right fender and the other vehicle had a scrape on its left rear quarter panel. There were no injuries reported at the scene.

Blast! I can't get anything right. It's too late to edit my original comment.

Well, that's awesome that Google reports on accidents outside of California too.

Thank you for correcting me, delroth.
