Colin Lang: Colin Lang in UBS, just so that we understand the definitions, when you refer to "feature complete self-driving," it sounds like you're talking level five, no geo-fence, is that what's expected by the end of year, just so we're all on the same thing.
Elon Musk: Yes.
Colin Lang: And then the regulatory process, I mean, have you talked to regulators about this? This seems quite an aggressive timeline from what other people have put out there. I mean, are they... you know, what are the hurdles that are needed and what is the timeline to get approval and do you need things like in California, I know they're tracking miles that, you know, it's an operator behind that. Do you need those things? What is that process going to look like?
Elon Musk: Yeah, we talk to regulators around the world all the time. As we introduce, you know, additional features like Navigate on Autopilot, we, you know... this requires regulatory approval on a per jurisdiction basis, so... But I think fundamentally regulators, in my experience, are convinced by data. So if you have a massive amount of data that shows that autonomy is safe, they listen to it. They may take... They may take time to digest the information. That process may take a bit of time, but they have always come to the right conclusion from what I've seen.
