These items are not in direct view of the road. Imagine a windscreen where data is interspersed on it your eye would be immediately distracted and often have difficulty discerning whether or not that is a pixel or a person in your view. And yes the police can pull you over for not having a fully clear windscreen. As stated this is nothing more than a stupid gimmick.
Does looking down or in the mirror whilst driving count as a lapse of concentration?
I imagine that if it were ever implemented that a driver would have to initiate the display. Simple on and off switch.
