It's beyond me that in the EU, Australia, Asia and other (developed) countries the laws are not being changed. In that respect I can be grateful that my children were born in the US. At least I know.
Same goes for boosters, in the US they advise all children up to 4yo and 40lbs to stay in harnassed seats. My 2 4yo are still in harnassed seats, my oldest is almost 7 and has just moved into a booster a few months ago. Again, there is so much research pointing into this direction ... why wouldn't you do what is safest for your children.
So please do your research.
Firstly, it's great that you are clearly so passionate about this topic but I have issues with the way you have expressed your opinion. Being an expat and a new parent is a tough job as it is, and your comments were not helpful to the point of being mildly offensive. Generally I believe that criticising the parenting choices and home country of others is not an effective way of getting your message across, but I do have some criticisms of my own.
Since we live in a city that doesn't appear to have any child restraint laws at all, I thought it was important to follow the regulations from somewhere else. To that end, I did do my research and found that Australian seat belt and child restraint laws are some of the toughest in the world; they were the first country to bring in compulsory seatbelt laws, and did so some 15 years before similar laws were adopted in the States, so I trust them when it comes to child restraint recommendations.

I did also look into the recommendations from the US and while it's great that the US is now being proactive about child safety in cars, it's a shame that the different laws in each state don't always apply to adults, nor, in some cases, children, and that the fines are so minimal that they're often ignored ("
Ideally, all infants and children in all vehicles should be covered by enforceable safety belt laws or child restraint laws or both. But differences in the way the laws in various states are worded result in many occupants, especially children, being covered by neither law." - Highway Loss Data Inst.). I think you'll find that the Australian laws regarding infant restraints are similar to those in the US (that you mentioned in your post), but they are nationwide and the ramifications for breaking them are so steep that they are more often obeyed than not.
Secondly, I agree that the videos are terrifying and the evidence for rear-facing infant seats is compelling, and yes, the thought of my child being injured in an accident fills me with dread, but I do believe that facing forward is best for him. There's no way I would let my son face forward if I genuinely believed he wasn't safe. Here in HK the furthest we drive is a 10km stretch on South Lantau, where we're more likely to run into a buffalo than have a head-on collision. I'm not trying to be blase about it, but there are a lot of factors that go into making a decision like this, and those factors are different for every parent. An educated choice based on the needs of all members of a family, no matter how different from your own, is not ignorant or irresponsible (as you imply) just different.
This is a serious issue and I do think living here where there aren't any rules makes it tough, but I think it's definitely a matter of preference and personal belief, and if you have guidelines to follow whether they're American, Australian, European or whatever, you should be educated about them and make a choice that's right for you and your family. I personally believe that having my son where he can see us and we can see him is safer than having him rear-facing and causing an almighty ruckus - which would be so distracting, and distressing, that our risk of an accident would increase exponentially.
