"Industry" is a keyword that your pedantry is overlooking. Unless you can edify us as to where there was an EV industry prior to Tesla? The existence or history of the tech is irrelevant in that comment.

The most important component in an EV is the battery. The lithium ion battery made electric cars practical.
So you could say Sony invented the electric car industry by being the first to commercialize lithium ion batteries:
