It's a little crazy to me that people are perfectly comfortable going 80+ down the freeway with no belts on in the back. Like the two seat backs are enough. It reminds me of the "no smoking sections" in restaurant that were sectioned off by a half wall.
Old UK safety video on this: https://www.youtube.com/watch?v=TWLmoeoHrP4
Are we supposed to believe that the front seat will somehow move forward from the force of the rear passenger hitting it? And this force will be so great that it will crush the front driver’s skull against the steering wheel? Is that really the take-away here?
If so, that’s a PSA about poor engineering and design of the driver seat and less about rear passenger seat belt safety.

That said, and more on topic: this isn't so much about laws as it is attitudes; plenty of people even today don't bother to wear seatbelts.
