The EU has been using a single mandatory tire-label system that has an "efficiency" category, among others, so that you can see the tradeoffs, since 2021.
But of course, the EU is over-regulated, let's laugh at the EU :-)
California is also over regulated.
IIf you’re over-regulated, you’re bound to get something right every once in a while. To over-regulate and get 100 % of regulations wrong would require someone in the system to be able to tell good from bad, aka competence.
