there are already a couple of free charging stations at the railway carparking grounds,since a couple of years,in the area where i live now.
time will tell if all of them will be free in the future.....

Yes, but it is only a temporary promotion for electric cars, not a global economic solution.

of course it is.first they give it for free(ive never seen any charging car there yet ) and in a couple of years when its more common you have to pay for it with,possibly with crypto (automatic/with IOTA as an example)
