Are we likely to see a shift to electric cars over the coming years ?

Not likely. First, to do so the government would have to people out of their conventional car comfort zone with laws and regulations but I guess the government is also more interested in reviving the conventional cars more than the electrical cars. Also, related with this the government would be pressured by oil countries which would not wan't a shift to electric cars since this would decrese their sales. Overall, if there is to be a shift to electric cars over the coming years I guess the people would have to really yearn and build a craze over electric cars but it seems to be that people are more comfortable with conventional cars more than electric cars.
