They provide good alternatives, indeed, but Tesla is still the most sold brand in Europe, and anyone living in Central Europe cannot deny that Tesla is by far the most dominant EV brand. The reason behind it is that there is pretty much nothing in that price range that offers the same as a Model 3 or Y... However, Tesla has sold more vehicles than the ones they can provide support to, so all their service centers are collapsed due to their dealership policy...

The European brands need to be more competitive, and although they are on good track for it, I think they are a bit late to the game. Is either that or people noticing that the after sales support of Tesla is inexistent and they start to value the perks of the legacy automakers.

That's because European brands offer more models so your top graphs are fragmented. This is how market competition looks like - having a choice of models and brands not just a single Tesla 3.

On top 10, European brands together vastly outsold Tesla - VAG group for example outsold all Tesla models in EU last year.
