Tesla is a good example of how a new auto manufacturer should operate, granted they received a gov low interest loan, they've got skin in the game and produce in the USA. Also, Ford is competing with a similar vehicle without gov loans.
The down side of Tesla is the max 270 miles on a four hour charge. Don't expect to get across country quick, especially using the heater or air conditioning.
Another problem is that if for some reason a Tesla's battery become depleted or below a minimum, the auto becomes what is called a "brick". A "brick" has to have the total battery pack replaced at owner's expense, $40,000, there is a prepaid plan for replacing batteries after their useful life, but not a "brick". There are also problems with towing a "brick"
If lots of consumers buy electric cars, there is going to be a problem with our electric grid. Even at present, in large metro areas, where electric autos make sense, they scramble to prevent rolling brown outs. This will only get worse as EPA regs shut down older coal fire plants. Hopefully, the gas from fracking will take up the slack.
I'm all for subsidizing research and even low interest gov loans where the majority risk is carried by the recipient.
