The ban is on new vehicles. ie: New vehicles sold after 2030 must be zero emission. Not that all existing petrol and diesel vehicles must suddenly be scrapped.

The ban is on new vehicles. ie: New vehicles sold after 2030 must be zero emission. Not that all existing petrol and diesel vehicles must suddenly be scrapped. Vehicles tend to last about 15 years, so even with a ban coming into effect in 2030, it'd likely be around 2045 before the vast majority of fossil burners are off the street. That's pretty gradual.
