My understanding is that the EU wanted us to have them here in the UK like on the Continent from a safety aspect but groups like the CAMC & CACC we’re opposed to it on behalf of their members incurring additional expense! Then the UK were also opposed to it because there was no infrastructure to do all the trailers & add them to the system and to create one would be too expensive! So cost won out over safety and this is where we are now & no longer a member of the EUIve never understood why caravans and car trailers arent required to have an MOT, even if it just said the tyres are not rotten and the lights actually work.
