The remote heads mounted on my dash were not in normal line of vision for driving. They were still within glancing range so eyes off the road wasn't a problem. As for the air-bags deploying and hitting the head, in that situation I really doubt I could care less! While that head might be damages, nothing else in the vehicle (people) would be.
If you want to be P.O.'ed about something, how about the wreaths of flowers, air-fresheners, and other stuff hung from mirrors?? Or that one @#$ fly that loves the windshield in front of you and your face!
