That's different from the previous auto-pilot version.
1 death in 230 million miles (so far) with Autopilot v1 vs 1 death per 90 million miles for non-autopilot.
"Autopilot v1" miles are also largely on freeways and conditions favorable to the driving-assist features. The 1 in 90 million is comparing to all cars and not just other cars with driving-assist. I don't think many people would argue that driving-assist is more dangerous than without. The 1 in 90 million is across far more driving conditions, many of which are more dangerous than what the Tesla Autopilot is driving in.
The comparison between the two isn't really a fair comparison and, in my opinion, is dishonest.
E:
In addition, picking any random model car may yield similar statistics. "Car accidents involving a Honda Civic per mile driven" is probably a lot higher than "Car accidents involving a Pontiac Firebird per mile driven". Because there are more Civics on the road... Firebirds may be in fewer accidents, but my money is on the Civic being a safer car.
I'm not saying humans react perfectly in these situations, but self-driving cars are rule-based, and have zero ability to adapt to unanticipated situations. I'm not arguing that Tesla shouldn't push forward. However, I believe that so far, Tesla has demonstrated a lack of concern for user safety. Companies like Google, Mercedes-Benz, etc. have tech at least as good as Tesla's, but have been much more cautious about deploying it.
