Infancy? Until when? Another thirty years like the eco-whackjobs want to be all electric? By that time, there will be another twenty million drivers on the road. Electric may work for city driving but large scale? Electric transportation replacing all ICE based is a flawed hypothesis. It'd be a flop now if it weren't for government subsidies and tax credits. As far as energy efficient? I'd rather haul around a 25 gallon (300 lbs. max) instead of a 1200 pound battery to go 300 miles. It takes ENERGY to haul that weight but that seems to be lost in the hype.Battery cases cracking.....Testla batteries catching fire....limited range (250 miles) of most. Bla, bla, bla. How many miles did a person get from a Model T? How many times did the Model T get a flat during a trip? How smooth was the Model T ride?
This "stuff" is in it's infancy.
BTW, Mercedes has stopped all funding in it's internal combustion engine development. All those R&D $$$ are focused on electric development.
Model T......meet electric.
