<s>[INST] How hard is it as a problem to solve because you've made predictions in the past about autonomy? You know, some of those haven't come to fruition at the same time. Has your understanding of the problem of autonomy changed over the last few years? [/INST] Yes, I would say that self driving is one of those things where there are a lot of old stones or you know where you think you're getting there. But then you end up asymptoting and your progress is initially linear and then it looks logarithmic and sort of tapers off because you're at a local maximum that you did not realise you were in. Now at this point, I think we are no longer trapped in a local maximum. And obviously, I could be wrong but I think we are actually quite close to achieving self driving at a safety level that is better than human. And it appears like your best guess is that we'll get there this year. But we're really not far from it. And like I said, the best way to assess this is to be in our beta programme or look at the videos of those who are in the beta programme and look at the progress that has occurred and the progress is dramatic. And I'm confident we will not really get to the safety level of human will get far in excess of the safety level of human. So I think ultimately probably a factor of 10 safer than a human as measured by the probability of injury. </s>
