Slava, hi. This is Vadim. Let me take this one. So look, I think, during the NDR [ph] earlier this summer, we were talking about self-driving technology vis-à-vis Rover technology, right. And one of the points we were making was that we believe that Rovers is the product that is, we can monetize earlier compared to self-driving cars. And this is due to the much more complex regulation that exists or, frankly, doesn't exist yet for self-driving cars. Rovers, on the other hand, they travel much slower, they're much smaller, they do not present danger to humans, etcetera, etcetera. And therefore, we see Grubhub partnership is something that allows us to test at scale the user case, whereby the Rover will actually substitute a couriers, right, for the last-mile delivery of whether it's going to be food from restaurants, or maybe like small parcels, etcetera, for e-com. And if you will look at the announcement itself, right, I mean, we did this partnership with Grubhub Campus, which operates at 250 university campuses in the U.S., which I think has a combined population of around 3 million students. The cool thing here, right, the Rovers, that uses somewhat -- they have a more limited use case, because they can only get to the building, but they cannot go up the stairs. And it works perfectly well in campuses, because the couriers typically are not allowed to enter dormitories. And therefore, the students are used to come down the stairs and pick up food. So this is going to be similar user experience, right? We're not going to sacrifice user experience in exchange for combining with Rovers. Now going back to SDG, the self-driving group, right, even though I did mention earlier that the regulation is going to take longer for us to get there, it depends country by country. At the same time, it's -- I do think it's important to mention that in Russia, there is a new Federal Law that was recently signed, which established regulatory sandbox for, call it digitally innovative products and projects. And we plan to use this opportunity in order to create regulatory sandboxes to in some places to switch to completely and fully autonomous taxis, and maybe even launch kind of fully autonomous taxi in one of the Moscow districts. The launches of those products or projects, is a function of government approval of those specific projects.
