Smart meters and smart chargers make it a snap to monitor electricity being used to charge a car.
Only if you have a smart meter, but there is no legal requirement to get one and it doesn't have to actually work as a "smart meter".
They were talking about taxing people who had the benefit of working from home so they need to charge for miles you don't drive as well!
Easy to game a system like that. Just tell the tax man you work at an office even if you never go there.
