So the tax payer should fund a network of dedicated charge points for short range PHEVs?
I'm not entirely sure what point you are trying to make here.
The taxpayer is funding our electrical driving activities already, to the tune of £5000 per new EV sold, £0 VED etc. Why has the government decided to do this? Because it recognises the two dreadful truths of Peak Oil and Anthopogenic Climate Change. I regard these tax breaks as them casting their bread upon the waters: when enough people are on board, to the extent that it's denting the revenue raised by the oil/ICE industry, the taxes will be swiftly transferred to electrical vehicles by one means or another.
The government has an enormous dilemma though. They are aware how many jobs are created by the oil industry, many of which will disappear when EVs are much more numerous: no huge fleets of tanker drivers on the road, far fewer oil refinery workers, fewer people to fix cars that don't need the elaborate servicing of the ICE. In short, the entire capitalist system is closely linked to the oil industry as it's where all the economic growth of the past 70 or so years has been generated. Without oil, our political masters, and their financial ones, are going to have to look for a different model.
