This is where the government needs to step in and say: 'you need to agree to a standard & progression timeline, and stick to it' -like when mobile device manufacturers agreed on the micro USB charging standard (now advanced to type-C). It should have actually been done on a global scale already, but we can only hope. Charging EV's shouldn't be something like the format wars (VHS/Betamax, Blu-ray/HD-DVD) where people are left stuck with a less functional or unsupported device.
edit: most people should be charging from home/work, most of the time, with 'superchargers' only being required for long distance travel
problem comes when one sees what the government and manufacturer's did to something like the GM EV1,
utterly destroy is, and crush the remaining ones, so nobody tries to build more.
Manufacturers and governments know the huge profits they make from conventional cars are so great
they will fight to protect them. in any way they can.
so I see them definitely NOT making a common charge plug,or common parts like batteries,
I see them, charging people for using their cards at EV charge points, and installing GPS trackers on the car to tax you on distance driven.
I also see then putting cool but worthless technology in EV's to pump up the price so the profits on an EV are vast.
or making them so hard to fix, most people trade in their Tesla for a conventional car, as soon as the warrenty is up.
dont forget EV's are nothing new, indeed they were popular back when the Ford model T was around, problem was no National Grids existed back then.
so they faded into obscurity, or niche applications like the golf cart or milk float.
can they make a resurface? I still dont know, if they came out with a simple,cheap reliable EV that anybody with some common sense could fix,
and made it cheap enough anybody could afford one, a model T if you will,
I sure other manufacturer's will all at once switch, and the rest will follow almost as quickly.
maybe then a common charge plug and a infrastructure will get set up.
but here locally, as in the rest of the world, EV's are a niche product, until they become vastly cheaper, more reliable and able to be fixed by Sipho in a shed, like the model T or a Citi golf.
