Theoretically, maybe. But completely practically, that info is available for cabs today, for example in NYC[1]. A determined person can even figure out if you tipped[2].
All that without doing anything illegal. It's just a matter of matching pick-up locations and timestamps to people of interest. Which should be easy in case of public officials and companies with known headquarters.

- danso 12y agoNo. This is not even remotely comparable. The Uber data would presumably contain identities and histories. The taxi cab data does not. And it is not simply "a matter of matching pick-up locations and timestamps to people of interest"...the only way to do that would be to actively surveil those people for a non-significant amount of time, and that's assuming they are taking the taxi on a regular basis...predicting the times they've taken one-off meetings would be futile. Another big difference: taxi destination is only in lat/lng. For Uber data, it's possible that much of the data is exact address (or at least corner) of the destination...because it's just easier to enter it in the address you want as a user rather than obfuscate it (obviously, people trying to cover their tracks would try to obfuscate, but why would the use Uber in the first place if they were that self-conscious?)
