@Turdle Try it yourself to test its cost, possibility, and convenience for one person, and now apply that cost and (in-) convenience to every person in the nation. Now, assume that the majority is a bunch of hard-heads who think the old way is better, so you have to convince them that your way is best, regardless of their bias. Now, overpower their bias without passing new laws, or raising taxes on the non-compliants, or offering monetary incentives to those who agree to comply. Physical possibility and better energy management are not the problems here - the real problems are the ones doing the pushing, and what else they're tying in with it.
I totally agree, your idea sounds great, the way you wrote it. The problem is that along with every word you wrote, there is an exploitation waiting to be used, that will inflict all manner of inconveniences, restrictions, and new or higher taxes by the ones who will be pushing it on us. We all know that theoretically, such a system is feasible, but we aren't so ignorant as to think the opportunity to shift to such a system wouldn't be exploited by the ones who have a consistent track record of exploiting everything possible to increase their own wealth, our beloved friends the politicians.
Good discussion in this thread, and it's true that the technology is constantly improving and shifting.
@Rick I understand that this forum aims to lower political friction by ignoring the subject, but the fact is that EV's and clean energy cannot be divorced from the politics that have married them. EV's, like every other piece of technology, have a great place in our society - just may be not on the public roads, may be not yet. A post you once made about the hardwired telephone in a prior thread about EV's comes to mind; the room-sized supercomputers boasting unbelievable megabytes of RAM for the first time come to mind. We now regularly use hand-held, wireless telephones with multi-core processors boasting many thousands of times more RAM, that can handle conference calls to several people around the globe, reliant upon a global system of networks, while simultaneously playing a video game (such as Fortnite) with 100 players around the globe on a separate system of networks, in less than 50 years of development - without encouragement or funding from the government.
If EV's and politics could be separated, I can see that the grid would open up to them on a nearly universal scale. Just like how E-mail replaced paper mail, cell phones replaced home phones, handheld calculators replaced clunky mechanical desktop units, and so many countless hundreds of other things have been superseded by newer options found to be more convenient and more affordable than their predecessors. All of this was founded upon the consumer market, and became the norm because the end consumers wanted to buy it because it was "better". The sustainability of a single item has never been a concern, except insofar as it costs, because the money goes to whoever sells the things that people want. If the battery-powered hand calculator is what people want, and the old desktop unit is going out of style, then in stead of making parts for the desktops, the companies will turn a profit by selling batteries for the handhelds. Shift in production and thus availability invariably comes with innovation in any given technology.
The Internet as a whole grew from Alexander Graham Bell's wonky telephone invention, and now allows end users, hackers, and governments to control our own, others, or targeted individuals' bank accounts, cars, home appliances, garage doors, security cameras, and basically everything else. Imagine how electric vehicles, allowed to flourish as the end users demand them, could advance beyond anything we can possibly dream of, within our own lifetimes.
