We do already have a pay per mile tax on fuel.
Hence Labour's Rachel Reeves, possible,
justification to add a 3p per mile tax, starting April 1st 2028 on EVs.
In the first instance they try to incentivise EV take-up and then they realise they are loosing tax on fuel to EV owners... lets ignore the 'luxury' tax bump on vehicles over £40k and the rate EV owners pay at fast chargers, and the tax on home services, etc, etc.
