Ah lads - you know I love ye all, but I don't see the point in discussing stuff that's just not going to happen. Ban cars? Pay extra tax at the petrol pump depending on what you earn? C'mon now. We're all grown ups here
Having a card you swipe and pop in a pin code that is associated to your ‘Revenue / Carbon Tax’ account isn’t exactly rocket science. You probably already do it with your bank card. You’d just be using a different card for fuel now everywhere.
Also paying your road tax via at the fuel pump has been on the go in many countries for years without a hitch.
