This seems long on hand-wringing, and short on actual problems.<p>For example, the article notes that cars recharging at night will help utility companies to even out their demand-curve. The article then worries about whether the utilities will want to run their network at full-capacity, and how having it always running would be a maintenance problem. But that's ridiculous, of course the utility companies want to run at higher capacity and sell more utility. If their network is being taxed, they (or a competitor) can build more power generation and the problem is solved.<p>Similarly, if the concern is around the peak/off-peak power pricing, these times can be adjusted (if, for example, the car recharging 5-7pm the new highest power consumption times).
