What technology? There is nothing to copy.
Electric cars have been around for over 100 years and Ford and GM have had the means to build an all electric vehicle decades ago. Its unfortunate that the people at the top of the food chain grow richer via Energy (oil, electricity, etc...) and dictate to the masses what is available.
The day Tesla Motors can produce and all electric car below $30K, go over 1,000 Km on a single charge and production can keep up with demands...Ford, GM..and the rest of the auto manufacturers...will fall.
No more wasted trips to the gas pumps to refuel
