I think Euro NCAP ratings would have more teeth if it was mandatory for manufacturers of standard passenger vehicles to submit a reference model for testing. Voluntary testing doesn't work since manufacturers would be averse to submit cars for testing if they thought they'd get a bad score. And while Euro NCAP does sometimes buy cars for testing, they don't do it for every make and model.
And if the cheapest dogshit cars on the road (Kia Picantos, Dacia Sandero's etc) can have buttons, dials, wipers and indicators then so should everything above it. Companies like Tesla remove controls to cheap out on having to make a part, but they attempt to pass this off as innovation when it puts people's lives at risk.
