Telsa exploded in value after a certain November event, it's worth more then the other Car companies period.
Now, but it wasn't always and it doesn't have to be so in the future. Remember Worldcom and the dotcom bubble? And in car manufacturing land, remember GM? One of the Big Three car manufacturers in the US (went bankrupt), Chrysler, another one of the Big Three is now a (tiny) label/brand from a Netherlands based car company (Stellantis).
Tesla => Musk have been making a TON of promises and braking almost every one of them. That is eventually going to bite them in the behind. And when something like the Cybertruck just isn't allowed on the European roads, no sales in the much more populated Europe isn't going to do great in sales if you only have five models of cars in your lineup.
At this point the Roadster 2 is vaporware, the Cybercab is very little more then a nicely dressed up drone and won't be allowed on European roads either. The Tesla Semi is in a similar boat...
Don't get me wrong, I would have loved to have had a level 5 autopilot Tesla car 10 years ago. But not only does Tesla/Musk make a lot of unrealistic promises, they also don't look/prepare for actual deployment beyond the US. Just look at the Tesla Powerwall, it took 10 years before they introduced that product in the UK/Germany (the rest of Europe is still SOL). And that is after they actually produced/sold the product in the US. Other companies/technologies overtake them in the meantime.
As an example, the Volkswagen Group has only 4% of the market cap of Tesla, has a revenue of almost 3.5 times that of Tesla (that should tell you something about the value of Tesla). It also sells more electric cars in Europe then Tesla (2023), even though the most popular model was the Tesla Model Y by a mile (or a kilometer as we like to say), when you primarily sell two types of cars on the European market and the competitor sells many more then that, together it adds up... Around 17.5% of the electric cars sold in 2023 in Europe were Tesla, the other 82.5% were other brands.
At this point I wouldn't want a Tesla Powerwall (if they even were available in my part of the world), why use LFP or LNMC batteries in your home when you have options for sodium-ion saltwater batteries (no thermal runaway). But ten years ago I was going "I want that!"... I don't drive, but for the longest time, if you asked me what kind of electric car to buy, it was a Tesla, but the last couple of years other manufacturers have caught up and these days I would say "I don't know!". And at this point, I'm only interested in buying an electric car if it can drive itself AND is allowed on the road in the Netherlands. Who's going to be the first company that makes that? I don't know, but I wouldn't place a bet at this point...
I personally prefer companies that under promise and over deliver, instead of what Tesla consistently does (over promise and under deliver).
