None of the cheaper seats have a chest clip. Isn't that unsafe?
It may just be that seats manufactured in the EU are cheaper to import to Israel.
The bottom line, though, is that the physics of car crashes are no different in Israel than in the US; the differences are all about the circumstances around and cultural attitudes toward car travel. I don't personally believe that Israeli children are less important or more difficult to injure than American children, so I would never argue that an expired seat is "good enough" in Israel if it's not here in the States.
