You can't really go by sales numbers. By that logic Apple would in need to "catch up" with others.
Its all about the quality and thats why we use macs even if the market shares are small for it. MacOS + the hardware is just win win that no one will be able to beat or even match (now that we are on AS chips).
Same goes for Tesla. Their charging network, efficiency, battery tech, design etc. is years away.
All the "serious Model Y competitors" you mentioned are not very good cars. Sure, they will sell more maybe but that doesn't mean they are better.
The only Tesla's problem is the quality control. Otherwise Tesla sits comfortably on the top and will sit there for a while.
First of all, sales numbers are important because they translate into revenue. Of course, it is a completely different thing to sell 100,000 small cars than 100,000 luxury cars. However, the sales figures I referred to include mostly cars in roughly the same segment as Tesla (Audi e-tron, Ford Mustang Mach-e, etc.) Car manufacturing is a well-known business where the profitability differences of similar cars are small between brands. You just cannot put a $10,000 premium in the price.
I do understand your point about Macs. To some extent the same applies to car brands, premium brands exist because some people are ready to pay extra for a car they like. On the other hand, comparing Apple with Apple Silicon to Tesla is not a good comparison, as AS offers something technologically superior and meaningful from the customer's perspective (fast chips with long battery life), whereas Tesla does not have anything similar at the moment. Compare Tesla Model S to M-B EQS, or compare Tesla Model Y to Kia EV6. Each of these cars have their strenghts and weaknesses, and the result depends on customer's preferences. It is a true competition.
An important thing to understand about the great success story of iPhone is that it was not about hardware (Nokia had better) or touchscreen (many brands had tried that). It was about infrastructure and platform. Without iTMS and App Store Apple would not be the clear leader in high-end smartphones. And the same applies to Microsoft. People do not use Windows and Office because they are so extremely nice, smooth, resource-saving, and otherwise likeable. People use MS products because everyone else uses them.
Similar platform game is not possible in the auto industry at least for a very long time. There seem to be two possible roads to market dominance:
1. EV charging (or battery swap) network.
2. Autonomous driving software.
The first one (EV charging network) is what Tesla has tried with its SuperCharger. The game seems to be over in many countries outside of the US, because regulators understand the importance of open charging networks for the local auto industry. For example, many European countries subsidise EV charging network development, but receiving the subsidies requires the network to be open to all brands. Cars can only be sold if their charging arrangements conform to common standards. Politicians all over the world are very much against subsidising foreign companies.
If some player comes up with truly useful Level 4 AV (car drives by itself in most conditions without any need for driver intervention), that player will have a very strong market position. However, this is not an easy road to market dominance. To gain a dominant position by AV technology, one would need to have several years' technology lead, and during those years the technology needs to be sold at a reasonable price, or it does not become widespread.
I repeat: Tesla has got some very good technology, and it has been the technology leader for a long time. Despite this, most other players are not aiming at beating Tesla because that would be pointless.
