Of course the cynics will jump on this story and say "I told you so" like they do for everything. I'm starting to think that there are mostly only cynics left on Slashdot : /
But it's more sober to assess the value by looking at the long term impact. The technology will change as they become more popular and advancing battery technology will make batteries more efficient to produce. The *concept* of electric vehicles can produce a society that has less energy waste, and less pollution, even if the first generation of vehicles do not meet the goal.
With the understanding that electric vehicles will eventually (fairly quickly actually) have a positive impact, we can ignore the short term impact so that:
* Charging standards can be matured
* Charging stations can proliferate
* Battery technology can mature
* Motor technology can mature
* Laws can mature
Thank god the same group of cynics didn't get to have an effect on computer technology in it's infancy.
