a lot of misinformation is quite normal with new/unknown technology. a major player introducing the technology with a serious effort to sell it competitively will help a great deal.
word of mouth will sell EVs. it is simply a question of how to get that word out. 10 years ago, the Prius got a huge boost in that regard when the state mandated that fleets be required to use alternative fuel vehicles when one can be found to fit the need. for basic transportation the best candidate was the Prius.
this literally force-fed the technology to state workers who were forced to drive the car as part of their state duties. many complained at first. they were confused by the controls, afraid of electrocution and other ridiculous random thoughts that run in people's heads when dealing with something new.
over time, that faded and resulted in WA State becoming one of the leaders in hybrid adoption. Well, WA State is now doing the same with EVs. and yes, it will probably take a few years like hybrids did.
hopefully, it will be a bit less due to a bigger intro (WA Started hybrids in 2002 when Prius was still in limited production) and more players in the EV game. i dont know how many Volts the state has acquired but do know that they have ordered several Leafs and MiEVs.
another thing to keep in mind. the amount of FUD only validates the technology. if there was nothing to worry about, the talk would fade away quickly. it has not and only because Big Oil knows that EVs are gaining traction daily and they are worried.
it is no longer a question of if, only when and how much
