It's a joke really considering batteries are a consumable. That is they'll need to be replaced at somepoint in the cars life... So the cost will see many electric cars on the scrap heap ready to be recycled once the batteries are spent.
Most new cars are disposable. Why would electric cars be any different?
What I'd really like to knows how long does a battery pack last before it needs to be replaced?
Personal transport has always been expensive. I don't want to even think about what I've e spent on cars over they years
