> Diesel is far worse than petrol for local pollution for example. So let's ban diesel in the city, then as electric becomes more viable, we can finally ban petrol as well.

This is less true than it used to be unfortunately. Most manufacturers have moved to Gasoline Direct Injection engines for efficiency reasons, but GDI engines produce a lot more particulates than regular gasoline engines, although not quite as many as diesel.
