Oh wow, let me reinforce that I did not said that in an offensive way, or at least not my intention.
Just google took kinda the wrong approach to the glass idea, but people are putting a tough wall to make it harder. I do think tho it will happen and become a standard someday, but I would expect it in 20~30 years from now.
And if what you call "sense of security" means "I don't want strangers to record me" you should not leave your home...and even at home be careful with what you have inside, since even mobile cameras can be use, just less sneaky.
tl;dr if people want to record you they will and if people want to distract themselves while driving they also will
