Another point I was getting as is that pure electric cars suffer from the same problem space rockets do: most of their weight is fuel.
Hence they are heavy, need a lot of raw material and manufacturing. Read: Expensive and bad for the environment, compared to a cheaper plug in hybrid.
And a tiny, 5 horsepower gasoline generator is hilarously efficient compared to a car engine. And dirt cheap, and weighs virtually nothing. There are technical reasons for this, but basically it's not even in the same league, and produces a fraction of the emissions as a full ICE car.
