It would take a smarter and better informed person than me, but it would be interesting to see what the break point would be between the CO2/environmental impact of replacing millions of cars, the civil engineering/materials cost of the charging infrastructure and the generation impact over say ten years versus reducing mileage on the existing infrastructure. Taking into account a true 'well to wheel' thorough audit of all the aspects.

If you take into account the larger environmental impact of manufacturing an EV and the payback time .... if the idea is to reduce the CO2 entering the environment as a matter of urgency .... it would be ironic if, over this critical couple of decades, just everyone reducing their mileage by 10 or 20% would make a greater actual practical 'real-world' difference than the current push to churn everything over that has the car manufacturers and civil engineers rubbing their hands at the billions to be made out of our enforced consumption of the 'new normal'
