The wisdom of the market:
The people who make cars have known for a very long time that their main product is not cars, it’s CO2 via coal to smelt metals. Doesn’t make much difference if there’s an internal combustion engine in it or a battery.
Many have decided to address this by making cars bigger and heavier.
In large part because the market does not want to price in something which it intentionally has ignored so that the secondary product is as profitable as possible
