Are we be anyway near total electric mobility in the car segment in next 10 to 20 years?

Although countries like China and Norway have gone fairly ahead in electric mobility, the world as a whole is still far away from a significant shift in electric mobility in the cars. As per the latest estimates we may end up having only 600000 or so electric cars in 2018. The cumulative total electric cars may just about cross 1.4 million numbers by 2018. The % of electric cars vs total cars rose from 0.48% in 2013 to 3% in 2018. The rate of growth in last 2 years being much more than the earlier gives a hope of an exponential growth the mid to long term.
