All electric cars need to carry the same generic, easily replaceable batteries. Then a filling station will be just like getting a new can of propane for your grill. Drive in, let an automated machine swap the batteries for fresh ones and drive off. The idea of hooking up 170,000 watt power source to my vehicle is not appealing either. The Galaxy Note 7 had a fancy fast charging circuit too.
I'm all for electric cars as long as they take over via the free market and not subsidized by tax dollars. That said, I am not in on a Tesla any time soon. I have a Suburban that holds 3 pinball machines and a Focus that gets 36mpg for daily driving. We are still a long way away from a true replacement for fossil fuels. Until then I would rather see every building in America get LED lights, thick insulation and two pane windows (all made in USA). Energy conservation is the way to go along with a major switch to nuclear power. We should also be drilling the shit out of the entire continent and stop buying foreign oil.
