One of the big things is the amount of lithium needed for the batteries and the amount that is easily available. Last i checked there is 88million tons of lithium with only a 1/4 of that easily available, its also a massive ecological disaster too wherever its processed and needs massive amounts of water, which pollutes the water table.

Batteries can be recycled but your only going to get 50% back at most, so the demand for lithium would grow, every 5-10 years your going to need a new battery.

That is not to say if they try to use lithium batteries for grid storage for solar and wind also will take up the supply of lithium.

I think the whole EV thing is so they can limit the amount of cars on the road to reduce people being able to travel, with the limited amount of lithium say in 10 years of using up the lithium its going to get even harder to replace your batteries.

Now if some miracle battery comes along this would change but it does not look that good overall.
