I hope that happens in the UK. Imagine 80% of the roads traffic sorned. Nice quiet roads....
It will never happen
#1 what would you do with the millions of trucks, cars, & buses that are powered by diesel? Not to mention diesel powered trains, & taxi cabs. The country would grind to a holt
#2 No Government could afford to lose such revenue from unpaid road funding licence, car insurance vat, fuel tax revenue loss. Not to mention loss in tax revenue from people not being able to get to work, due to no trains, cabs, cars or buses because of a ban on diesel.
#3 everything that is in your home including your fridge & food cupboard, once travled in an Articulated lorry, power by diesel.
So no Asda, Tesco, ect. The shelves would be empty. As i type food & stock is being delivered, to meet important needs. Again in diesel trucks
