Very true - BUT it does seem to me that there are many “full circles” being turned by nervous governments responding in a knee-jerk way to unproven environmentalist claims.
Don’t forget that back in 1998, the EU promoted diesel as a more environmentally friendly fuel, with lower fuel taxes than petrol, etc. Now, improved design of petrol engines means diesel no longer holds any climate change advantage, so diesel is the fuel of the devil! However, against all expectations, sales of diesel cars in UK haven’t plummeted as forecast. Emission level changes may have been an indirect cause here. That said, there was a large drop in 2017.
So, what will change / reverse in the next 20 yrs??
