Let's start with this segment of the title:
"Teslas Aren’t Safer On Autopilot"
Then, further down:
"Teslas are not safer with Autopilot on"
"Of the 2.1M miles between accidents in manual mode, 840,000 would be on freeway and 1.26M off of it. For the 3.07M miles in autopilot, 2.9M would be on freeway and just 192,000 off of it. So the manual record is roughly one accident per 1.55M miles off-freeway and per 4.65M miles on-freeway. But the Autopilot record ballparks to 1.1M miles between accidents off freeway and 3.5M on-freeway.
In other words, about 30% longer without an “accident” in manual (with forward collision avoidance on) or TACC than in Autopilot. Instead of being safer with Autopilot, it looks like a Tesla is slightly less safe.
But not a lot less safe. And if the predicted 3:1 ratio of accidents freeeway to non-freeway is too high, it might even be about the same. But almost certainly not 1.5 times better as Tesla’s numbers imply."
Which I think is a pretty fair and even handed evaluation of the available data.
