I don't have mine yet, so my comments are officially hearsay. It's my understanding that the driver is only warned (on both the center screen and the heads up display) if the real-time image recognition decides that what it's seeing is a human in the road or someone on a bicycle.
Hmm, it sounds to me as if the wizards at BMW don't feel that a deer, bear, dog, coyote, or any other kind of critter is a concern to their drivers. Perhaps a little less artificial intelligence might be useful. For example, Is something in the road? Yes - warn the driver! Isn't it that simple?
