Nonono, I think you still misunderstand a bit. Electric cars are good. It is a step in the right direction. The problem is the perception that many people have that gasoline cars are the main problem and switching to electric is what's needed. The argument by the author is against the rhetoric of electric cars, not against electric cars themselves.

All of what you said is what needs to be done (and more), so we should use rhetoric that acknowledges that cars are only a part of the problem.
