Tesla Robotaxis Are Crashing More Than 12 Times as Frequently as Human Drivers

This is a most excellent place for technology news and articles.
They gave you all the numbers you need to calculate the sample size for the Robotaxis, and it's safe to assume the sample size for regular cars will be much higher.
I don't see how this gives sample size, are you considering every mile a sample?
i'm not worried about the sample size for regular cars but there's like 10 of these driving right now.
Basically yes. You can't usefully put a car into one of "crashes" or "doesn't crash" categories the way you can with e.g. what colour an M&M is, or whether Drug X did or didn't lower blood pressure in a patient, so miles travelled is a reasonable metric.
It's possible you might be getting hung up on notions of sample size having to be above a particular fixed number and therefore miles sounding like a cheat, but actually there never has been a universal "correct" minimum sample size; it all depends on the data. A billion of one thing might not be enough, but 4 of another might be plenty.
Let's put it this way. If you knew a person, and that person just had their fourth crash in 8 years having driven 160k miles, would you think "this person is a bad driver" or would you think "they only crashed 4 times, let's see where this goes".
Especially if you've seen this driver drive in the wrong lane, go straight in a turn only lane, and other dodgy maneuvers regularly.
