A lot of what you says makes sense. Except " Also, the need to somehow recycle and dispose of all of the internal combustion engine cars would be a problem. "

A lot of what you says makes sense. Except " Also, the need to somehow recycle and dispose of all of the internal combustion engine cars would be a problem. " We are already well equipped to recycle and otherwise dispose of worn out combustion vehicles. I don't think anybody expects electric cars to accelerate the need for that - existing cars will continue get used by the increasingly less affluent until they are worn out, just like they do now. They aren't going to all just get scrapped tomorrow because electric cars become more common - they will continue to age out of the fleet, just like they do now.
