I think there are two issues here, the first being we all hoped the taxation incentives would have lasted a little longer having bought arguably more expensive cars with the benefit of lower ongoing costs.
The second bigger issue how our taxes are spent. Our infrastructure is creaking, the power network ,water and railways all need massive spending. Our military is a shadow of its former self, the NHS is crumbling and the road network is appalling. Yet we spend stupid amounts of money on projects like HS2, even the smallest change to a road junction requires spending the best part of £100k on consultation before a 6 figure sum is spent on doing the work. Then there's the money given to their 'mates' by the government for consultation, sub standard PPE etc. We all recognise 3p per mile as the thin end of the wedge, along with frozen tax bands.
