People use to say the same thing about planes, gas cars, computers, cell phone and most new technologies … guess what … they just kept getting better and better … my bet is the electric cars, batteries, and charging units will get better over time … are we ready for full time use of electric cars … no, but it will happen … just a matter of time.
I don't think your analogy applies to electric cars though. Everything you sited represents clear and enormous gains in function. Flying comfortably to the west coast in 5 hours beats driving for two days and driving for two days beats the hell out of spending months using horse drawn coaches.
What we're talking about with electric cars is a switch from gas/diesel powered vehicles to electric powered ones. There is no correspondingly big improvement in function. Will the electric cars be bigger? Will they carry more load or people? Will they be safer? Will they be faster? What are the benefits of the switch? There was never any doubt of the benefit of a cell phone compared to a land line phone. Or a computers benefit. Or a planes benefit.
Sure there MAY be environmental benefits. But even here I would want an honest assessment of the environmental cost of the battery production and electrical grid maintenance of an electric car fleet versus a gasoline powered fleet. I suspect that the true environmental benefit here is marginal. And if the environment is the driving force wouldn't a switch to a natural gas powered vehicle fleet be a better option?
And given that the USA possesses the largest reserves of coal, oil and natural gas on earth can someone explain the economic benefits of converting our gas/diesel powered vehicles to electric?
