ALL the Tesla drivers are taking the bus because their $50,000+ "car of the future" can't run in the cold. Looks like consumers will still be buying a vehicle with an internal combustion engine, not one with unreliable batteries.
Granola power doesn't work very well when you're outside California, it seems...
I can get around 700 - 750 miles of range at 48 - 50 mpg with my turbocharged diesel (the most thermally efficient internal combustion engine). When an electric car can do that, it will be a viable long-term alternative.
Speaking of efficiency, what are the total losses involved in converting stored energy (coal, hydrocarbon, solar, wind or atomic) into electricity, transmitting it to an endpoint, converting it to DC to charge the batteries and transferring the current to the motors?
