It was exactly the same when incandescent light bulbs were banned. The alternatives weren't as good and almost no improvements were made. After the ban it took like 5-10 years, but suddenly there was progress. By now even halogen lamps are gone, because LED became so much better. And in the end it's not the fault of the legislation. If it wouldn't be so common to go above the limit there wouldn't have been any need to a beeping device. Just look at those idiots still arguing about their tachometer being 10% off, always, and therefore thinking it's fine to always go 5-10 km/h above the limit, never below.
