Because it's true. Most EU countries aren't built to have 100% EV. Not every country is Norway. Spanish or Czech grids collapse from hot weather already, how much worse would it be when you suddenly plug millions of vehicles? With 220V one would need 1-2 days to fully charge continuously to get to 100% depending on battery size; perfect timing is a wishful thinking, you'd get peak charging times as well. Speed chargers are very few and their price is now approaching gas prices already, and electric grid can't bear many of them anyway.
