The debate on pollution from vehicles tends to distract one from the real sources of pollution, such as coal burning power stations. It is a fact that Germany and France are increasing their reliance on coal , ( in the case of Germany they are burning Lignite - brown Coal , which is even more polluting ) Their arrogance is unbelievable given that Germany hosted a climate change conference last week in which they lectured everyone on increased emissions whilst increasing their own carbon dioxide emissions. See the following report: https://instituteforenergyresearch.org/analysis/france-germany-turn-coal/
Attacking motorists while ignoring a far greater cause of pollution is Kafkaesque and grossly unfair
Only for new cars though and no impact on commercial vehicles which are the ones that you see most emitting foul clouds of smoke under load. So another half-assed attempt to do something that won't have any real impact on the problem thus allowing them to have a second bite at the cherry next year.
To be honest I see possible improvements in areas like this to be the only benefit of Brexit. Instead of having to get emissions controls agreed across the EU we can simply set our own tests and targets and deal with the issue. I don't see this happening though. It'll just be tinkering with things and hoping electric and self driving comes along quickly enough that they can then penalise massively anyone that doesn't jump onboard.
