There's a fairly steady stream of posts here about data/privacy/etc. It's easy to pillory companies for violating privacy rules in various ways or mishandling data. However, given that data can't be reliably anonymized and that a lot of things that happen in public have simply never been systematically recorded in the past, there are a lot of fundamental questions over what sorts of data should be recorded when they provide legitimate value to users.

As a hypothetical, what if autonomous driving is seen to depend on what many would see as invasive data collection and monitoring? Should it be permitted? That's a hypothetical, but I don't think there's an obvious answer to the question as posed.
