Four other factors will assure this as well......
1). TAXES. As more EV's are on the road Local, state and Government entities will push for higher and higher EV taxes (many already are). This will have a cooling effect on EV sales since right now all the electric charges are being given away free to entice consumers into the market. Which leads to number 2
2). COSTS. Right now most EV drivers are enjoying a heyday of free energy as the government and EV manufacturers use FREE stuff to lure customers in. Eventually consumers will be shocked to see it's no longer "free" to charge their vehicles and this will cool demand.
3). AVAILABILITY As more people drive EV's the electric grid will begin to face brown and black outs. The infrastructure to support a transition to EV's simply does not exist.
40. EOL issues Right now very few people are concerned about End Of Life of these EV's. But as large groups of people come to the battery end of life cycle and face the enormous cost of battery replacement, it will become widely known that they have been lured into a costly cycle with EV's.
