I'm one of the few driving an electric car.  I think, that the switch takes a leap of faith, but once you make the move, there is no looking back.
At this point, the greatest limitation I see is the range which could be helped by better charging station network OR further developing the technology of roads (or at least highways) with built-in charging lanes (so you would never have to stop to charge).
I understand why so many are skeptical, but its' probably the same sentiment as the introduction of the combustion engine cars in the early 1900s.  People ridiculed and questioned it and then we figured out the 'how'.
