Did you watch the video? Because that's exactly what he says. The whole issue boils down to the fact that the regulations are outdated, not that there are conflicting regulations.
Worth noting is that even if the regulations could be worded better, nothing is stopping Hyundai from doing it correctly. It's not forbidden by regulation, most other manufacturers get it right.
Regulations are there to help in cases like this. If the regulation is failing to accommodate modern vehicles, they need to be changed. Trusting companies to "get it right" on their own and act in the best interest of peoples' safety leads to unnecessary deaths. Seriously, back when seatbelts were invented car manufacturers were almost completely against it. They lobbied against regulations to implement them.
Luckily, at the very end of the video, it's actually revealed that a couple of months ago the new regulations were put into action (about a decade late)
