Sales slowing is only one variable in the “growth” equation. Specifically, are sales of gas vehicles slowing more than sales of electric cars? Yes.
People are replacing vehicles at some standard rate, but growth of EVs is dependent on what percentage of new vehicle sales are gas versus electric. As long as people aren’t moving back to gas cars en masse, the growth of the segment can continue to rise, even if sales overall are slowing.
Said it better than I could. Fair? Yes. Effective? No.
