Sometimes, we must face reality. Newly developed safety features are a selling point and people do pay more for safer cars. If law dictated (and enforced) that all cars must have the exact same safety features, there would be no financial incentive to develop better safety, or much less incentive at least. In reality, car safety features are one of the few examples of things actually trickling down: today's cheapest cars have safety features that at some point only existed in the most expensive luxury cars. This is fine.
None of this applies to whatever the fuck the original post is about though.
