Bad quote. He didn't say "L4" - he answered a question that used the phrase L4.
The correct quote is - FSD Beta will be better than humans in terms of "failure rates" this year. He has not clearly defined what rates he is looking at, though.

Thank you. And the last question from investors is, Elon mentioned Level 4 autonomy could be achieved this year. Is it based off initial FSD beta rollout experience, or is Level 4 ability predicated on Dojo being completed online?
Elon Musk -- Chief Executive Officer and Product Architect
As mentioned earlier, Dojo is not required for full self-driving. You know, it should have a positive effect on the cost of training networks. You know, it's not just a question like does it get to full self-driving but really kind of like the "march of nines" of reliability, is it 99.999% reliable or 99.999999% reliable. This is -- it gets nutty.
So, obviously, we want to get to close to perfection as possible. So, frankly, being safe than human is a low standard, not a high standard. People are very, very lossy, often distracted, tired, you know, texting. Anyway, it's remarkable that we don't have more accidents.
So, it's -- yeah. So actually being better than a human, I think, is relatively very forward, frankly, how do you be 1,000% better or 10,000% better. Yeah, that's what, you know, gets much harder. But I think anyone who's been in the FSD beta program, I mean, if they were just to plot the progress of the beta interventions per mile, it's obviously trending to, you know, a very small number of interventions per mile and pace of improvement is fast.
And there's several profound improvements to the FSD stack that are coming, you know, in the next few months. So, yeah, I would be shocked if we do not achieve full self-driving safer than human this year. I would be shocked.
