Electric cars is an incredibly old Tech (older than ICE, even), since the very first cars invented were electric.

Tesla were just updating an old tech and trying to make it viable (in which they succeeded), by using modern batteries and electric motors instead of what was used in the original EVs.

The innovative Tech stuff was things like automated parking and automated driving. I don’t think integrating what’s basically a tablet on a car dashboard counts as innovative Tech - it’s the same kind of thing makers of “Smart” Fridges were doing - grab old tech, put a touch screen on it and call it high tech.

Without this high tech part, Tesla is just a company that went into the market for car manufacturing with a strategy of carve out a new market segment by updating to the XXI century a technology from the XIX century that is now cheaper to run and adresses the Ecological concerns of many people - quite a smart and in some was innovative business strategy but it makes them no more a Tech company than Mercedes-Benz is a Tech company for having invented Electronic Fuel Injection or Uber or my local supermarket is a Tech company because of they have a smartphone customer loyalty app.
