I am sure that battery sizes can be reduced by 2040, and if they are still too heavy, someone would have to invent a contraption for garages to use when replacing batteries.
If there are no straight forward ways to replace batteries, someone is going to have to come up with an alternative solution that is practical. The only one I have at the moment is hydrogen fuelled cars. Although expensive at present, the price will come down with mass production and competition.
