Everything you stated is true, except the scam part. The EV's that we have created thus far are rife with faults, however the evolution of all technologies begin with faults and failures, these are stepping stones to future developments and innovations. Lithium ion tech is not the solution for large scale energy storage, however it is fairly ideal for smaller disposable devices. The energy density storage capacity is currently the reigning champion of small batteries. The need for more advanced and less toxic resource requirements will change the future of home energy storage, personal conveyance and mass transit. We are still in a relatively early stage of development. Try to keep an open mind and try not to discourage the continued development of emerging technology. The dream of individual power production and long term independence from big corporations' stream of consumable fuels is the goal.
