I hear very frequently that Tesla isn't a car company, it's a tech company. Mostly because they want to value Tesla stock like a tech company (very popular, high valuations, high profit margins), not a car company (cyclical sales, lower profit margins, heavily regulated).
But whatever Tesla is now, eventually if it sells cars it has to turn into a car company. It has to deal with things like logistics for spare parts, repair facilities, dealers (or whatever way they choose to sell cars). The fixed costs as Tesla goes on are only going to go up because of the legacy they are creating, as cars last a while (hopefully a long while), and need to be maintained/repaired, if only because of accidents.
Tech, on the other hand, usually means you don't have to worry about physical manufacturing. You don't have to worry so much about supply logistics, travel and transport costs, inventory, etc. Once you build the technology, at least with software it's easy to mass reproduce (especially with digital distribution and no physical media) at low overhead and sell at a reasonable price, sometimes direct to the user (higher profit %).
Now let's talk about another case study of a consumer discretionary company that uses tech a lot, Amazon. Amazon is leveraging tech to help the front end and the supply chain, to provide lower prices and easy shopping to people. By making a great website, they encourage people to find and buy more, attacking the "browsing at the supermarket" theory of impulse buying with their own impulse buys. They are using technology to do logistics cheaper, lowering prices to gain market share.
Tesla, and car companies in general, move a lot slower because people aren't buying cars every day. Do I think Tesla could turn into a great car maker? Sure.
But just because there's a new space (EVs) doesn't mean that current companies will own the space going forward, or even the leader today. Tesla is using its startup-ness to try to get there, but will they get over the hump of actually turning profitable while making cars? That's the big question, and if the futures earnings are in the stock price, that's a bet I'd rather pass. (but wouldn't short either)
