I wouldn't call it a "real business" just yet. I've heard they do 50,000 rides per week in SF, LA, Phoenix combined. Assuming they make $20/ride, that's still $1M/week, or $52M/year. I'm sure they spend in Billions/year. They would have to scale out to every major city in America and add another 10000 cars before they can turn a profit.
