This is my take on upcoming EV competitions:
Europeans:
VW is going big, as well as Volvo/Polestar. Both ID3/Polestar2 are proven to be a cheaper (in either price and substance) alternative.
And that is the keypoint of the $25000 model from Tesla. VW and Polestar are basically choices with compromises.
We all know Tesla is not only a pioneer in the EV space, but it produces the best EV there is, bar none. What VW/Volvo and other EU manufacturers are hoping that with their current infrastructure of dealerships and manufacturing know-hows, they might stand an edge (regardless of how irrational it might sound) against Tesla.
However, I think the way Tesla is doing is that their EV requires little to no service, and hence there really is no need to have a massive dealership network to service the vehicles. Sure I wish Tesla's service capacity could be better reading all the stories because I never know when it's going to be my turn. However, in my own experience, I've ever needed the service once, and that's for more a cosmetic issue (misaligned door) rather than anything else.
Most of the bugs are solved via OTA updates. And thus, in the grand scheme of things, legacy's infrastructure is not really an edge, but more of a burden that it's going to drag them down in the long term. As we can see from many examples, like Jaguar's OTA capability needs to be "enabled" by dealers. This business choice, I believe it wasn't Jaguar's original intention. However, they've got no choice.
Chinese:
NIO, BYD, Xpeng... etc are all going full steam after the Chinese market. However, the advantage that Tesla has is not so different to Apple's iPhone. It's considered a premium brand in the EV sector. And with Tesla continuing effort to optimize cost and reflects almost immediately to the market, it makes Chinese brands really hard to compete because many still have the model year mentality where they make adjustments on a year-to-year basis.
Thus, I think it doesn't matter whether it's competition from European/American/Chinese EV brands, Tesla's business decision (no-dealership model, no model year model, charging station infrastructure... etc) is what separates itself from all the competition.
Eventually, I believe many players, if they were to stay competitive, they'd have no choice but to mimic Tesla's model. However, given the news we got from Battery Day... by the time competition finally copies everything Tesla CURRENTLY has, Tesla would move to somewhere else already as far as competitive advantage goes.
