Thailand managed to ramp up the distribution of LPG and CNG for vehicles very quickly. But, that was at a time when liquid fuel was expensive and the conversion from petrol to gas was relatively cheap, so the demand for LPG and CNG increased rather rapidly.
I don't see the same thing happening with electric vehicles until the prices comes way down. Establishing a network of electric stations should be cheaper and easier than it was for LPG/CNG, but until the demand is there progress is going to be slow.
