 The entire world has pretty similar pedestrian signals, except for the US and Canada. Oh, really? Yeah. So that's when we started expanding here. We needed to travel a bit here to capture a lot of data here to make sure that the algorithm was very powerful here as well. And then now, of course, as people are using it, we're constantly gathering imaging information to maintain that algorithm to make sure that it stays performant. What's different about the US with respect to our signals?
