So, you think your partner is cheating on you with their ex. You know they got a taxi from your apartment last Sunday at 6pm, you look up the data, and sure enough, the taxi went to the ex's address, and not home as your partner claimed.

Or, you arrive at work late, claiming that you stopped off at a client's before heading in to work, but your employer can now verify that you actually got the taxi from your home address.

I'm assuming in these examples that you just need to know pick-up OR drop-off - if you need both, then I agree with you that it's not much of a concern.
