In my Old expertise of engineering of Aircraft, especially Helicopters.
The Scientific world can see the improvments in personal transport towards EV pilotless craft. Batteries are improving all the time, to the point of of lithium Ion, much lighter, but needing different charging systems. Boeing and Airbus are investigating highly.
China is producing beween 30% to 60 % of there elecrtic power from . coal. India will not go Electric vechcles, according to JLR. Due to the infrastucture.of the country. Which I can understand, having lived ther for 3 years.
So we are left to the compound areas of the European and The United States of America. Which is so large , that EV will be a just in the citys. Due to availability of recharging, I am sure they would rather be Hybrid , with maybe in the sunnier areas with Solar panels.
Don't get me wrong I love the EV's the power, etc. But when will all the goverment and utilitys companies go EV vehicles.
