Think electric cars are a good idea?

Maybe you should read this:

Tesla Motors’ Devastating Design Problem

Tesla Motors' lineup of all-electric vehicles — its existing Roadster, almost certainly its impending Model S, and possibly its future Model X — apparently suffer from a severe limitation that can largely destroy the value of the vehicle. If the battery is ever totally discharged, the owner is left with what Tesla describes as a "brick": a completely immobile vehicle that cannot be started or even pushed down the street. The only known remedy is for the owner to pay Tesla approximately $40,000 to replace the entire battery. Unlike practically every other modern car problem, neither Tesla's warranty nor typical car insurance policies provide any protection from this major financial loss. Here's how it happens.

Despite this "brick" scenario having occurred several times already, Tesla has publicly downplayed the severity of battery depletion risk to both existing owners and future buyers. Privately though, Tesla has gone to great lengths to prevent this potentially brand-destroying incident from happening more often, including possibly engaging in GPS tracking of a vehicle without the owner's knowledge.

The Chevy Volt and Nissan Leaf use essentially the same kind of battery - although with the Volt, you might be able to drive on the gas engine if for some reason the battery died dead.
Tesla engineers must have had to put in overtime to figure out how to make a car's wheels lock up solid when the battery dies. Sounds like a lot of extra effort was expended to get that feature working.

So, when your government-supported Volt needs a new battery pack, at least it won't cost $40K, as the federal government will simply steal yet more $$$ from us to help you buy a new one.
