My car is only a few years old, so yes, it has air bags all over.
Luckily they have not been opened as I have heard some nasty stories about the pressure of them opening. However I still believe this is far better than the alternative of not having any and smashing your head into something in the event of a bad accident.
Are back seat airbags a thing? I've never heard of that. One of the reasons children aren't supposed to ride in the front seat is that the passenger side airbag is at a height that it can break their necks instead of saving them in an accident. I would have thought that would be a problem with backseat airbags. We have them in the front. Touching wood we haven't had to use them so far.
Maybe it is side, come to think of it Jennifer!
I know some of the sVU's have 7 in total so actually they must also be in the back seat and I would think that by now they would have sorted out the back seat ones, and children?
