Every electric car slated to arrive has been called a Tesla killer in article after article, sometimes individually, often as a collective.

Several of them are targeting Tesla owners with discounts, ads at superchargers, etc... The companies clearly think they are competing with Tesla, especially since they don't want to compete with themselves (ICE models).

As for doing their own thing, most have a battery shortage and are confined to small cars with relatively small battery packs for now until more batteries are available (none of whom are vertically integrating production).
