Current battery tech for EV's is only good for short range commuters who have a means to charge from their homes. That leaves out half the population.
Hybrid EVs are pretty good for everything. Their batts are small enough to be easily replaced when they go bad (all EV's of every type will have their batteries need replaced in 10 to 20 years time) and you don't need to plug them in so no range issues or priving unregulated EV charging station to worry about finding.
That's really the only type of EV the US should be concentrating on until there's better battery options available. A 1500 Lb Battery that costs over $10,000 to have replaced so you can go 300 miles when the car is new (and temps are warm) and have it slowly dwindle down lower and lower with every charge is a waste that will prematurely add vehicles to landfills.
