In the US, what sells the most (sadly) are pickup trucks and SUVs. The numbers aren't even close. The big automakers here know this, and have tailored their product lines accordingly. Ford is basically kept afloat singularly by F-series pickup sales, and have cancelled many sedans entirely. They have an entire range of different sized trucks and SUVs for every market segment. Same with Chevrolet. Now pan over to Tesla. Tesla has one single SUV offering, and sales of that SUV are dismal. They just teased a pickup truck release with their 'cybertruck' product, but the design was purposely off-putting, and it only served to make a mockery of the market segment. So with one SUV that doesn't sell, and a parody of what is currently the highest selling platform in the US, I'm not sure why anyone speculates Tesla is in a place of upward trajectory. I don't buy the argument that other car companies can't/won't pivot to counter either. Porsche reverse engineered one of their Model S vehicles, admitted it was quite well-constructed, and then countered with the Taycan (by all reviews a better car) a mere 3-4 years later. I'm glad a company like Tesla exists to force the market to the EV concept, but most people will buy an EV when they know it's supported by a long established and trusted automaker like Toyota, Ford, Chevy, or Honda. Tesla then exists as a proof-of-concept model for the bigger players to follow, not as a displacement.
It should also be noted, many motor companies are also investing quite a bit of money into alternative fuels like synthetic petrol and hydrogen, and don't want to rely on an energy source which is primarily derived from conflict zones. They aren't 100% sold yet that the EV platform is indeed the way forward.
