True?

I don't know how true this is, but this post makes a good case that there's a conspiracy to not implement quality electric cars:

For many years the car companies have said the "the batteries aren't ready" .... and I'm sick of reading it. They are in fact so "ready" that within a few months to a year 3 relativley small automakers (further details below) will be thumbing their noses at the big 4 auto companies as they bring to market electric cars (and a pickup) with 300-700hp electric motors, 100mph+ top speed and 100-200+ mile ranges per charge. Which might lead many to ask, "why are car companies saying the batteries not ready".

This post contains everything you've ever wanted to know about the state of electric cars, the technology of batteries and implies the question, why aren't we using it?
