Longevity of lithium as a key resource, page-19

I loved the bit when someone ask "how do you know it will reach parity by 2020-2022"  his answer was the only thing keeping EVs more expensive is the cost of batteries. As technology continues improving the costs will keep dropping and batteries are getting better, the data is showing that's what is and will continue to happen.. he also said everything else costs the same apart from EV motors which are cheaper than Gus gusslers. Now factor in all the other saving based on owning the car, cheaper to run, cheaper to maintain and better longevity. It's a no brainer.
