I wonder if manufacturers of LPG Retrofit Kits lodged a protest?
I'm sure they did. Can you imagine the costs they'd have to bear? The kits would go up, the economics of retrofitting would be in the toilet and they'd end up going out of business.
What may have also had an impact is that the major manufacturers are all located in what the EU considers to be less affluent countries (specifically Italy) so the socio-economic impact on these regions would be much higher than in a major industrialised nation. I suspect some Eurocrat thought it was a good idea until they actually thought about it a bit!
