 Figuring out how to get more people in fewer cars is really what we're all about. So think of the world where there is no ride sharing, and people are driving themselves to work, let's just say. You now have 30 people being served by 30 cars. Those 30 cars are only served 4% of the day, 96% of the day, they're stored somewhere. That takes up 20% to 30% of our land is just storing these hunks of metal that we drive around for 4% of the day. And so you go, well, we could do better, so Uber rolls out and then, well, it's one car serving 30 people instead of 30 cars. And then we do something like Uber Pool where you push a button, car comes, you open the door, you get in, but there's somebody else already in the car because two people are taking the same trip at the same time.
