If I remember correctly, the actual point of the signs in car windows is to alert emergency services to a child being in the vehicle in case the vehicle is in an accident. I could be incorrect however, it was just an explanation I heard decades ago at this point.

I have one for my pixel 7. I also put a small square of electrical tape over my front camera. I know I sound paranoid, but I just don’t like a camera staring at me while I’m looking at my phone. I also rarely take selfies so a front camera is pretty much pointless for me.

I do once in awhile, usually if I see a good looking pot roast on sale. I usually use this recipe, it’s for beef stew but it also works as the liquid for a pot roast. https://www.fromvalerieskitchen.com/classic-stovetop-beef-stew/#wprm-recipe-container-60964
