Why on Earth didn't they looked at the data on whether it was engaged? Surely Tesla has this.
I don't know the details on what Autopilot installation entailed, but collision avoidance and warning systems, not to mention automatic braking, save lives and tons of crashes, especially smaller ones. The seem to have appeared in 2015 on the Model S. They're on high end cars and one reason why late model cars are so much safer.
Autopilot could be significantly more dangerous, yet attenuated by collision avoidance systems. For example:

FCW with AEB reduced front-to-rear-crash rates 50% and front-to-rear injury crash rates 56%.
That's a huge drop in airbag deployments. This is what Tesla added to Model S in 2015, and in X. They're separate systems to "Autopilot". I imagine basic lane keeping and lane leaving warning systems reduce crash rates further. They do in other cars - many BMW models have zero deaths despite more cars on the road than Tesla.
By the way, these early systems were MobileEye systems. Tesla did in house after breaking up with them in 2016, and released shoddy in-house work soon after - work so bad that lead engineers quit after disagreements with Musk about releasing it while unsafe.
It would be nice to have hard data.
