The electric vehicle market is still evolving. There are products in the figurative pipeline that could be monumental, and the charging network has not yet sorted itself out. I understand that Tesla is making converters (not the correct term) that would allow "others" to use their charging network, which will be a complete game changer.
GM in particular has products coming that could be the best available in their segment (e.g., the Blazer EV, the Silverado EV). Tesla is threatening to produce a smaller, less expensive car (under $30k), and the CyberTruck is still looming.
Nobody really knows if or when the explosion of EV's will impact The Grid, if at all. But it's possible. Utilities could very well tell residential consumers what hours THEY MAY CHARGE THEIR EV's.
When will states start to impose an EV road tax, to substitute for the gasoline taxes that EV owners are not paying (they do use the roads, eh?)? How about the Feds? Same thing. How will this impact the economics of buying and owning an EV? Yet to be seen.
As a car nut, I personally think it would be foolish to jump the gun and buy an EV right now. In 18 months, the selection will be twice what it is now, and "we"will have a better fix on which products are doing well and which are problematic.
