A Tesla S battery weighs pretty much the same as a new Caterham. 540KG vs +-545KG.
A Tesla S weighs 2.2 Metric Tons. Four Caterham's. Then we have the energy required and environmental damage expended to construct such a material rich behemoth.
I propose it's all a load of stinking politically driven pooh but what do I know?! Save nuclear, we still need to burn carbon rich energy to provide the power to charge the Tesla and all EV's. It's just 3D chess.
Put that in your pipe, smoke it and discuss!
Footnote - I've not had a decent game of chess in years. What a fantastic game of strategy that is. I just go steaming in and see what happens. Much more fun!
