I don't care. I think that even if it is unavoidable it is very much worthwhile to resist and to indicate as early and as often as possible what is and is not acceptable. The only times when it is worth giving up some of your privacy is (1) when it is with your active consent and (2) when there is a tangible benefit to you and (3) as a result you are not causing 'collateral damage' to the privacy of others (who have not given their consent). Privacy is a great good and giving it up should be done very carefully lest we all end up regretting this in ways that can not be undone.

It must be my overactive imagination but I can see so many ways in which this data can be abused that there is no possible upside that I'm willing to trade for. Consent withdrawn and if the last taxi is outfitted with facial recognition software I'll be happy to walk.
