What makes you say that? The camera looks like it's in a place where you should be able to see it. Either way, I don't think a conversation I have in the back of someone else's car is private.
Because I find it incredibly hard to believe that he would engage like this if he believed there was a possibility of the conversation being made public. Sure, I could be wrong, but I am of the camp that the driver will find legal repercussions to this.
