The problem has been the battery: the amount of charge it could hold and the weight of it. The bigger the battery, the more charge it holds, but the more it weighs. The two all-time best selling electric cars, the Nissan Leaf and the Tesla Model S, have EPA-rated ranges reaching up to 151 mi (243 km) and 335 mi (539 km) respectively, according to Wikipedia.

The solution suggested by A Brief History of the Future is the carbon sandwich battery. This is what it says:
In 2060 researchers looked again at electric eels and were able to develop carbon sandwich batteries which not only held more charge than traditional batteries, but were far lighter and less polluting. Electric motors quickly replaced liquid fuels in the 2060s in both the developed and the developing worlds. World demand for led and oil plummeted as carbon batteries became cheaper.

Charging points were also a problem until enough people were convinced that electric cars were the coming thing and set up charging points in enough places. A chicken and egg situation indeed.
But it seems that this will be a reality a lot sooner than 2060.
