Yeah, but you could also use it to see where cars are in the area and track them down from there? Except if you're a cop they flagged and they send you bullshit noise on purpose. I guess that's fine, right?
Yes, it is fine. Uber is a private company and its data is private. It's an interesting thought experiment but I just can't get behind the idea that a private company has a moral or ethical responsibility to ensure that data they're providing to the public via their own app doesn't mislead law enforcement. If there was a court order for the data and it was inaccurate or false that's one thing but this is completely different.
