My 2015 Tesla S has ten year old technology and does DC fast charging. It's a solved problem. You can buy a Dongfeng Nammi Box compact car with 42 kWh battery 310 km WLTP range for 169 kNOK in Norway, that's 14.3 kEUR but it's probably more expensive in the rest of Europe. Still it's much cheaper and can DC charge at 70 kW.

If you live in a flat as many do in the Netherlands DC fast charging might well be the only practical way to charge a vehicle. So I think this is just a toy for the well off who have off street parking.
