> those programs are going to become mandatory
I would say the jury is still out if it makes financial sence. Batteries lose capacity to aging even if you don't use them.
This is extremely speculative and if the government has appetite to make anything mandatory about cars, they would start by enforcing the speed limit electronically
Not at all.
The EVs' batteries are used as storage, which can help with intermittent electricity production but it implies two things assuming it can work at all:
1. enough electricity is produced overall,
2. the grid has the capacity to move all that electricity around.
These are the two issues I initially mentioned and using EVs' batteries as temporary storage solves neither.
