There's a lot of myths around EU legislation* but 90% of the EU legislation is implemented promptly simply because they are simply useful - like standardisation of marking or even VAT invoices.
And there's a whole range of directives that *are* being delayed due to various national-level interests - for example air quality directives were delayed by Polish gov *against* the will of most citizens simply to please coal mining industry.
