If the Front facing cameras had the ability to pivot inside the houseing it would have better field of vision to the sides at intersections. It would be similar to a human turning his head to look both ways. Apologies if this was already discussed, but I didn't see it.
There are actually 5 cameras facing forward, and they provide a pretty good field of view already. Go to Autopilot and expand the "Learn more about Camera Views..." section.
