Who on Earth refers to electric vehicles as "e-cars"? Lol
EVs or BEVs is the terminology I've always heard.
That aside, I don't really see how European companies can compete at the low end without slapping tariffs on Chinese goods. Europe doesn't have the benefit of things like forced labour.
Also, I think it's unwise to allow our reliance on China to grow even further. We've seen from Russia that making a hostile nation integral to our economies not only makes us reluctant to hold them to account properly, but it also causes us tremendous disruption if we do go about severing ties.
