I don't think that's a realistic assessment of where Tesla is at as a car company. Tesla is still not very good at the actual making of cars. For example, in the last five years Tesla has had more health and safety violations in their factory than the top ten automakers in the US combined:

Tesla cars have among the worst reliability of any car brand:

Consumer Reports no longer recommends the Model 3 due to its lack of reliability:

In 2018, Toyota and Volkswagen each sold over 10 million cars:

Whereas Tesla has sold about 550,000 cars in 11 years:

Volkswagen is starting its push into EVs. They'll be releasing multiple electric models across multiple brands every year from now on. Porsche, Audi, VW, Skoda, and SEAT to start. I'm sure there'll be electric Lamborghinis, Bentleys, and Bugattis eventually (if you're in the market for those):

Volkswagen also wants to license its MEB electric car platform to other manufacturers. They already have one licensee:

I think Tesla's main problems are that they are a small car company with an erratic CEO, inefficient and unreliable manufacturing, and they're about to face a lot of electric car competition from one of the biggest car companies in the world.
