But passing this tax will affect all future IPO's. If the city wants to take a hard line with Uber, then do that. But don't pass a tax that affects all companies going public. That just puts an incentive for startups to move outside the city before going public. Is that a good thing? Is that what the city of SF wants? I don't know, but giving a reason for all these workers to commute up and down the peninsula seems silly. Especially because CalTrain is already insanely crowded as are the roads.
