Taxes are so incredibly high in the EU and EVs have substantial VAT and registration exemptions to the point where a Prius would be the same price as a Tesla Model Y in some countries.

You can get a brand new Prius OTD for ~30k USD in most of the US, but you aren't getting a Prius for less than 45k EUR (50k USD) in most of Europe, and then you also have to pay 8 dollars per gallon to fill it up.

Imagine if you had to choose between a 50k Prius or a 55k Tesla (after subsidies), and you can see why these higher end EVs are doing so well.
