Interesting video. One thing I noticed is that he focused on cost to "run," not cost to own. Take the iMiEV, for example. It costs $43,000 to buy (before government incentives). The Aygo costs $10,753 to buy. How many miles will he have to drive his iMiEV before he recoups the cost difference?

The iMiEV electricity cost $0.30 for 14 miles: 30/14 = 2.14 cents/mile.

The Aygo gas cost $0.92 for the same distance. 92/14 = 6.57 cents/mile.

So the iMiEV saves him: 6.57 - 2.14 = 4.43 cents/mile.

$43,000 - $10,753 = $32,257 price difference.

$32,257/$0.0443 = 727,923 miles he'd have to drive the iMiEV just to break even on the price. After that he'd start actually saving some money.

I highly doubt the car would last that long. But if it did, how many times would he have to replace the battery pack and at what cost?

And he says that if the powerplant is coal fired the carbon footprint is 30-40 % lower. Not much better than the ICE cars. I don't think too many people are going to pay the huge price difference for a small reduction in CO2 output.
