Of course EVs are perhaps a net benefit to society (noise, pollution etc) but at least be honest about the cost trajectory.

Any article that doesn't mention the cost of motorway/dual carriage way electric charging is being disingenuous. PAYG is 75-90p/kWh currently. Tesla superchargers with a subscription 57p/kWh (you'll pay with time, due to being busy)

And do you think when EV ownership becomes more popular, the 4p/kWh home charging rate is going to stick around? That is an insane discount compared to daytime electricity.

The UK does not have a good, cheap solution plentiful cheap electric in the next decade or two, so any major increase in demand will mean even higher costs.
