It'll eventually come down, but what we need is more infrastructure. MOre charging stations along main highways and rest areas.
I'm not getting how building more charging stations will reduce the purchase price of electric cars.
I'm also not getting how the cost of electric cars can come down dramatically (like the way the cost of VCR's and computers came down). 90% of an electric car is just a car - tires, bodywork, interior, etc. - we've had 100+ years to bring those components all the way down their cost curve. The remaining 10% will get cheaper, but by how much? The stuff that goes into the batteries is scarce, hard to handle, and has a finite lifespan.
Sure electric cars are a neat technology (despite being powered by coal in many areas). But I don't think they are a panacea.
