Yeah I think that's probably true but as a private company we don't know how significant these costs are. I think it's questionable to have a business plan predicated on suing your way out of being considered a taxi when in pretty much every way that matters, except one, it's a taxi (or limo, or a hybrid) service. And that one exception is that it has a decent Ux in large part due the Uber app and its backend infra (which is huge).
