This is a good question. So let me just go back to my prepared remarks comments and just elaborate a little bit from there. We have a 20-plus year history in our technology. Our team builds last on safety into every product from the ground up. So that's actually a very, very important part of it. And I'm actually very proud of our culture on making sure from the ground of things are built right. We've been doing demos for customers and all the units we demonstrate are Class I safe, meaning that the features are implemented. Since we're in a demo phase, a MicroVision representative, our VP of BD or myself are always present there, in most cases, both of us are there. I can say with confidence that our team has done a great job of implementing our virtual protective housing for Class I. The safety -- the demos are going like going incredibly well actually, and OEMs require that the demo unit is fully conformed into Class I standards and the company representatives are present when we go to these demos. So that's part of a foundational piece you have to build out. And I think the question is, was the Class I certification in Q3? Is Class I certification needed to use a LIDAR and public, right? So as I just explained, for demo, that's the gap that they've created, right, or essentially, that's what the regulation allows. When you think about full certification, as move to sales, that's when you have to actually get the full certification done. FDA approval, go outside third-party, whatever other testing you have to do. But for that to happen, you have to have all your features locked in, everything is into the RTL, everything is locked out, and then you submit the final sample that comes to customers will buy. Once we start selling it, it has to have full conformance whereas OEMs and Tier 1s are very, very comfortable taking those samples, they needed to be Class I certified because at that point, there's no company representative, and they will do their other confidential testing that they will not discuss as a course. So, I think like to sell a product, we certainly have to have full certification. But to demo product, you have to have the full feature implemented operating in full safe mode with the company representative available. And this is not just new to us, every company has done any kind of deal in LiDAR or anything with a 95-nanometer laser or any kind of laser in the history of time, has to go through the same process. So, we're very comfortable with this process and I think we have this objective well in hand.
