Not everyone hates their ex, you know; it just might be emotionally difficult to be reminded of the loss.

What would be the point in downvoting in the first place, then? I assumed it was a joke.

I understood it as a private, personal, downvote. Meaning to tell the system to avoid that route as much as it's possible

Yes. I didn’t mean it as a social filtering thing like HN. I meant it more like most of us interact with Netflix (stop showing me movies like this, it was awful).

That said, if everyone hates an intersection, the mapping people should investigate why. Use it as a priority queue for audits, for instance.

Of course, if it's really about avoiding your ex, why would you want the makers to know at all? You'd really want the preference to be on-device only with an option to contribute it to everyone else.

Ah, I see! That makes sense.
