There's literally no way you know this for a fact.

There's literally no way in which I expressed it as being known as a fact by me.

Did you make sure to reply like this to poster I replied to as well?

The comment you are replying to starts with "My day-to-day experience..."

Yes and then go on to say something they could not possibly know for a fact. In my day to day experience Cruise cars are, mile for mile, far worse than human drivers . How could I possibly know that? I've had a couple bad encounters with Cruise cars but I've had countless encounters with human drivers in between all those. How could either of us possibly know which one is better "mile for mile." It's a ridiculous thing to say. By couching it with "in my experience" they attempt to make it sound like they're just talking about their personal experience but then they go on to say something that sounds rather objective and _could_ be measured (but wasn't).

Scene: dopamean and their partner get home from the grocery store with a trunk full of groceries. dopamean's partner knows dopamean has had a tough week at work and wants to do something nice for them.

dopamean's partner: "Hey dopamean, in my experience, the grocery bags full of canned goods are heavier than the ones full of chips. Let me take the heavier ones and you can take the lighter ones!"

dopamean: infuriated "How could you possibly know which bags are heavier? It's a ridiculous thing to say. By couching it with 'in my experience' you attempt to make it sound like you're just talking about your personal experience but then you go on to say something that sounds objective and _could_ be measured but wasn't! Did you weigh each bag to determine their objective heft? No!"

dopamean's partner: distraught "I'm so sorry, dopamean! I will never again share informed personal experience with you about objective matters without first conducting a rigorous measurement program beforehand to confirm my priors. Thank you for showing me just how much better I can be! I can tell you're so much smarter than me and I can learn so much from you."

dopamean: angrier than anyone has ever been "Oh 'I'm so much smarter than you' am I? You fail yet again! Did you measure my IQ, did you measure yours?? Have you learned nothing!? I could easily be 3 or even 4 standard deviations below your IQ!"

Fin.

“The long tail” are usually what causes safety issues, though. Easily identifiable and relatively high probability events are the ones more commonly mitigated. The low-probability events are the ones that tend to fall through the cracks and tend not to be obvious except in hindsight.

Should Cruise be compared to drivers as a whole? If a subset of drivers were restricted to a max speed of 30 MPH and drove very conservatively (like most CDL holders), they too would seem safer than the public. The public as a whole includes those who cut off fellow motorists, use their phone while driving, drive while drunk/high/groggy, etc.
