The average age of a car currently on the road in Romania, Bulgaria and Greece is about 16 years old. How do you think all those people with 16 year old beaters, will suddenly be able to afford the 20k cars?
They can also be upgraded to increase their range using after market batteries.
So we’re already at 15 years and counting.
Maybe the batteries will wear out, but what will a replacement battery cost in 10 years? Presumably even less than now.
The comment by Lio beside this one also makes it hard for me to take a view like yours.
