There is constant progress in Li-ion chemistry.
I know since I keep informed about batteries in general. I worked in a government battery lab and the fact that I know something about batteries and charging systems might explain why I get 16 and 14 years out of a "conventional lead acid battery" (not a fancy AGM or Lithium battery) in my vehicles.
But as everybody who owns an EV, they continue to think they are a "zero emissions" vehicle as the Nissan nameplate on the back of a Leaf claims. Pure BS of course. Electricity production (coal, nuclear, wind, solar), battery production and disposal and other factors.

I might buy an EV when it makes financial sense and is practical (charge time, range, battery long term life as in 12+ years and still have the same range).
I just did an out the door price comparison of a base Tesla 3 (where I included the $5000 rebate) to another ICE base vehicle in the same size class. The ICE vehicle got me over 8 years of free gas (based on 20,000 km per year, fuel efficiency and the present cost of gas) till I reached the out the door price of the Tesla 3 and that EV owner still needed to charge it for that same time period. I could have looked at a Leaf, but that would have made no difference financially.
No thanks!
