When CA legislators 1st planned for Zero emission cars, it was in the 1990's. Now Nissan is setting up charging infrastructue & EV's, without the state holding a gun to their head. The 1st EV infrastructure was limited to a few spots where the RAV4-EV's, the EV-1's and a few other EV's would be leased (and in a handfull of exceptions, sold). Enter 2010, and the Nissan Leaf. About 4 weeks ago, the San Francisco Bay area anounced plans to work with Nissan to set up charging stations. These will supplement home charging, while much of the non-home design will be for fast charge. Slowly the industry is making the commitment: http://www.nissanusa.com/leaf-electric-car/news-expanded.jsp?item=22#/car/intro I hope Nissan's effort is colaterally building a fire under Toyota's feet. .
If the places are convenient & reasonably priced I believe they will succeed. The charging interface also needs to be standardized.
