Regarding Texas, I have the following points:
- The law specifically mentions "attached to windshield" but not "rear view mirror." It also mentions "Obstruction." Accordingly, the law would make for an interesting case for "rear view mirror" mounted devices. Would like to check case law when I have some time.
- The way the law is stated, if "rear view mirror" mounted smartphones are "obstruction" then so is every single rear window sticker, rear view mirror charm, and dashboard bob-head. . . I want to say that ~30% of the cars I see have something like this, so perhaps this is just another dumb Texas law that is almost never enforced.
- If they are actively enforcing this for people who are using apps like Waze, then they are killing people every year by their stupidity, and I feel morally obligated to resist this out-of-date and very stupid law. I hope I do get a ticket so that I can be the first to loudly fight it.
