There are a bunch of unanswered questions (and by that I mean not yet litigated differences in opinion) with respect to glass.
For example, if you're driving and you notice you are being tailed, and you say 'Glass record' and you look down at your speedometer, and up at your rear view mirror, and then record the entire traffic stop. Is that video admissible in court? There have been stories of police officers being less than truthful in how a stop occurred, video makes that harder. There is also the infamous 'resisting arrest' charge which people of various demographics feel is used when profiling to hassle them. So if you can get it on record that it is illegal to drive with Glass, then you make it more obvious if someone reaches over and puts on their glass when they get pulled over.
Another question, is it a phone or not? It has a cellular connection capability so kind of. If its a phone are you 'texting' when it is showing text? Who knows, some would argue yes, some would argue no. Again, not yet litigated.
All these things are going to come through the courts eventually if this product gets any traction. So did the CHP tell their officers to add this if they stopped someone? I don't know but I can't think of any reason an officer would try 'watching tv' as the infraction.
