Have you seen Polestar's pricing? They're very much positioned as the premium EV option and their pricing is pretty much the opposite of dumping.

Commercial airliners cost tens of millions of dollars, does that imply a company that makes them isn't being subsidized by their government?

China subsidizes (among other things) battery manufacturing, which is the biggest single cost for making EVs. If you get your batteries cheaper than competing companies then you can make premium cars with an electric range at the high end of the market and then use the subsidized cost to provide other amenities that cause customers to choose your product over alternatives even at a premium price. It allows you to take the high end of the market on value just as well as the low end on cost.
