Sure. Hey Doug, this is Brian. Let me start and then I'm going to hand off to John. Look, we definitely played offense in Q3 to invest and supply and improve service levels. And we're tapering because we see more drivers returning to the platform and as Logan pointed out, they're giving more rides. And there's three contributing factors: the sunsetting of enhanced federal unemployment benefits, it's this increase in productivity, and there's also a pool of potential drivers who are being cautious, so let me just touch on each of these. We believe the sunsetting of enhanced federal unemployment benefits is acting as a tailwind. It's too early to tell the long-term impact. But in September, driver activation, so these would be new drivers, jumped 17% month-over-month and grew further in October. And if you look at the full third quarter, driver activations, again, these would be new drivers, increased 60% year-over-year. And it's important to understand, and I feel at times, the market doesn't understand this. Last year, 85% of drivers drove less than 10 hours per week on our platform. The significant majority of drivers are using the Lyft platform for supplemental income. And so, if you're getting $300 per week from the federal government plus whatever the state added, it really eliminated the need for some folks to drive for supplemental income purposes. And again, the jump in new drivers after the enhanced benefits expired is really providing some organic tailwinds. Second, as Logan pointed out, productivity has increased on the platform. And so when analyzing supply, you don't have to look at just the number of new drivers, but it's also just understanding how many rides per driver. And we've seen the number of rides per driver increase versus pre-COVID. So as Logan mentioned, in Q3, the number of riders -- sorry, the number of rides per driver was more than 20% greater than Q3 of 2019. And then finally, there are some conscious people who have not yet resumed driving or apply to drive, and there's different reasons. Some have concerns about the most recent surge and have a preference to wait for boosters. There are parents who are waiting until their kids are vaccinated, and others just don't want to drive all day wearing a mask. And so, I think conditions are expected to improve over the coming months. And as this happens, we expect to see people shift from delivery to rideshare, where earnings tend to be higher based on historical studies.
