I don't particularly like the Volt, mainly, because I think the price point is to high for a Chevy. I do think that the plug-in hybrid will be the transition genre to all-electric vehicles on a mass scale. My reasoning is that the plug-in relieves the fear of being stuck out in the boonies with no charger available that is high on surveys about why folks are not jumping on electrics.
Personally, I'm waiting for the Tesla sedan so that I can jump in all the way.
