Yes. Okay. So, now production lines that can make A-Sample, which is the first step, except they take sample design and go through reliability and other things. And it could be available for direct sales to anybody, obviously. Beyond that, the real answer to your question is, that if, let's say, an OEM was interested in something, you have stages, B-Sample, C-Sample and so on, which is their development cycles. So whenever they're enforcing decision, right, because it’s step by step. There are always in the market standard features that everybody's aware of. And standard qualification of what NHTSA wants, and what NCAP wants and what Euro NCAP wants, those are standards. But then OEMs, each OEM, because they're competing in the same market with each other, they have their own confidential things behind that. So it’s just -- it's a hard question to answer. But the point is, those phases is what they stack out, they look at the maturity of the technology, and look at the maturity of the company and look at the maturity of the supply chain. It's a safety critical device that's going to have a 15-year tail; they want to make sure that they can support it for that long. So those are all the things that goes into it. So as far as the qualification, once they have a target in 2024-2025 model years, it's backtracking, its pretty well known what the decisions will be and how you would go and how they're valued. So the production line, the way to think about it is, it's a demonstration obviously. There's nobody in the world that can actually demonstrate that level of scalability. The whole concept of -- excuse me, perfect LiDAR. I'm using bunny ears on the phone here. That the perfect ladder is not just about the features, it's also about scalability, long-term cost, reliability, proving all of those things. And this production line, we'll just another flower to show off what we've done all the time. They wanted to emphasize over 20 years. It's not the first time we've done this. We've done this multiple times successfully. So I think we're in a good position to demonstrate that. But really, that schedule is controlled by individually OEM, there's no general steps except what’s generally knows that they're after A-, B-, C- and so on Sample to mass production, or serial production.
