If safety is such a big deal, how do trucks still have blind spots, drivers sitting too high and non-mandatory side guards? These are design flaws.
It seems the "safety" interpretation here doesn't apply to everyone else not involved.

The big deal is to make sure that the companies are able to operate and pass the safety checks with a sufficiently high mark. Since those are based on the existing vehicles, there is no reason to redesign everything to get the same rating at the end.
Frankly there are much scarier issues to deal with, such as trucks losing their load, tire quality, "running the scales", etc...
