@mekkaokereke I disagree with how China did it but I agree with the sentiment. On the other hand, I don't think electric cars are going to help the environment much long term. Single owner-operated vehicles are massive polluters, period.
EVs tend to do their polluting at different phases of operation, but they are bad, albiet not as bad.
If we wanted our actions to impact the environment, a better solution is high-speed rail.
