If you come out to Cali we have plenty of charge stations, but even we are still a ways out from Japans EV infrastructure. I think the problem is, is that there is a huge inconsistency across regions in terms of support for electric cars. Whether it be incentives or availability of charge stations.
It comes down to practicality and cost of ownership, people wanting both have been buying cheap gasoline engine compacts. Its going to take a while for things to pick up but with the increase ranges we have to work with, a little planning of where you can charge and for how long goes a long way.
