All the naysayers and their mislead opinions..
I for one am really happy that at least some movement is being made in Electric car tech.
Without the current car manufacturers getting on board, there'll be no options to deal with the dwindling oil supplies, rocketing costs and associated political turmoil until it's much too late..(read expensive)
The fact that centrally generated power is MUCH more efficient than millions of independent ( and often badly maintained ) Internal combustion engines. ( something along the lines of 80% of a car's engine is used... to move the parts of the engine )
By the way, Producing petrol is very expensive. It takes a bucket load more energy to find, drill for, protect, pump, ship, refine and transport to your petrol station than most people realise.
At least electric cars have the benefit of using the best tech available for power generation. Be it Coal, Gas, Wind, Solar, GeoThermal, Tidal, Nuclear Fission or perhaps fusion soon.
You seriously want to be stuck with needing petrol or diesel?
