""We have not yet decided when to commercialize the technology,"
Meaning : "The CIA is very, very interested in buying our patent outright and we're waiting on the final figure before we decide not to go public".
Okay, gratuitous trolling aside, this is clearly spy tech that is at the limit of magic. On the other hand, it's weird enough listening to half a conversation when you hear someone else speaking on a phone but can't make out the words. This is going to be an order of magnitude above that. Suddenly the driver starts speaking out loud, and nobody is answering. Not to mention the potential for quid-pro-quo when the passenger thinks the driver is talking to him.
It really sounds like neat tech, but I'm not convinced the car is the place to use it.
