California regulators say Uber, Lyft and Sidecar's car-pool services are illegal

Uber CEO Travis Kalanick, during a talk earlier this week at the TechCrunch Disrupt conference in San Francisco, admitted that car-pooling is tough, partly because it requires that other passengers request the ride at just the right place at a certain time. And not every user, even in today's connected digital age, wants to share their ride with a stranger.

But Uber, which now operates in 45 countries across the world, expects regulatory challenges. The company recently hired David Plouffe, a former campaign manager for President Barack Obama, partly to help it fight all manner of regulatory battles. In California now, a new one apparently awaits.
