Been thinking the same myself. This is purely my own speculation, but I can see taxation of diesel at the pump skyrocketing in the next two years.
All these plans to scrap petrol and diesel engines by year X are clearly not genuine, and people see that.
No democratic government in the western world as an authority horizon further away than the next election - so rather than trying to ban something that may or may not ever take, it just seems more practical and more likely to just keep pushing up the price of the fuel by taxation until it no longer makes sense for anyone.
Bonus: you don't need to offer a scrappage bribe from the public purse either.
