Comment on Tesla Robotaxis Are Crashing More Than 12 Times as Frequently as Human Drivers
communist@lemmy.frozeninferno.xyz 20 hours agoit’s correct that 8 is not the sample size, but they didn’t give the sample size, it would be how many cars there are and the number of miles, not just the number of miles, they also didn’t establish fault and this was with a human in the loop, i’m all for hating elon but this isn’t worth reporting without more info.

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?

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.

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.
