Voice Activation gets to know your voice... question mark?

Hey all, just picked up my Tideland BC this week, and my dealer, who was in every other way respectable, told me this:

"The voice-activation feature learns the voice of the driver and will improve over time."

Not realizing he was riding with an Artificial Intelligence academic, he was then faced with questions about the learning algoritm used, the actions it would use as feedback for determining success or failure, etc. All of these questions were met with "I don't know"s so my personal BS detector stayed pretty low. If it's incorrect, I suspect he doesn't realize.

Has anyone heard about this? (I couldn't find anything in the manual, but I've spent too much time driving to do an exhaustive search.) While possible, I think it's much more likely he's got it backward... the driver learns the system.

Fill me in!

Wow. That's a lot of anger, which I can understand, given the supply shortfall and the occasional unscrupulous dealer. But they're not all that way. It's a very tough decision: put money in a liar's pocket to get the car sooner, or do a little extra work to find somebody straight-forward and honest, and maybe wait a little longer. Yet another real nice thing about a Prius is that it's much easier to spot the BS'ers than with other cars.

side question:
I had the nav system route me to work, for which it came up with a pretty horrible route. (In my case, it's better to get on street A, then take street B, and get back on street A to finish it off. The nav system would have me stay on street A the whole way.) I instead just drove as I usually do, going A-B-A, and the next time I asked for it to find a route, it gave me back the "good" route! Is this a quirk, foible, or feature?
