I can't figure out why, from the perspective of an auto ,consumer, so many people think the 4680 cells will be all that different from 2170 cells which are proven safe, durable and powerful and fast to charge.. The 2170's are proven to be these things over years and have low risk. Of course, I think the 4680's will prove to be all these things too, but the single biggest advantage of 4680 cells is the lower cost to manufacture. Obviously, there are other benefits but it's not like you will be driving down the road saying "Wow, gee whiz, feel how strong and nice these 4680 cells feel compared to those plebian 2170's."
It certainly wouldn't make me change my car buying schedule if I needed a new car.
