IMHO its basic risk vs benefit management.
If Eyesight doesn't act up with a dashcam placed in the no-zone and actually causes an accident, then the only detriment is if it doesn't act to save you from a potential accident. An aware driver, as one should be, can mitigate this risk.
If an accident does occur, for which you're not at fault, the dashcam video becomes invaluable.
Both of these situations should be very rare occurrences but the benefits vastly outweigh the risks for me, YMMV.

Just be glad our Eyesight acts the way it does. Honda's makes me feel unsafe:
Don't signal before changing lanes? It slams on the brakes when you cross that dotted line! (inconsistently)
Set adaptive cruise control? Maybe it'll maintain speed. Maybe it'll see a car 2 lanes over and slam on the brakes. Maybe it'll just pick another speed to maintain.
Ok, rant over
