There could be some very significant advantages to every home and business having V2G systems. People could charge up at night when demand is light and power homes and business during the day when demand is high. V2G EVs will give us opportunities to balance the grid that were never possible before.
This by no means would meet electrical code. This would have you potentially pulling close to 200 amps through a meter base and service wire only rated to 100 amps.As an electrician, I think you would be ok, your Ford charger will draw a lot of power when only used. I would even hook it up at my house that is only 100amp. the way power is distributed in most houses is that its only fused at panel with main breaker, I would add a wire splitter before the 100amp house panel and add a seconded 100amp panel for the charger. This way power is still measured by the meter base and also there are no fuses on the city side before your meter base to the transformer its hooked up to on city side. As long as you not charging a fleet of vehicles at same time this should work.
The diagram is very crewed but I don't think you can justify the statement that the intent of the diagram doesn't meet the electrical code. It's very likely that the meter is already rated for 200 amps but of course you would have to do your homework to be sure. And as far as the feeders from the meter go, you are going to have to replace those anyway to get the transfer switch/EVSE in there.
The problem is, that charging the electric vehicles still requires drawing electricity from the grid, and you are going to use a lot of that electricity driving. The net result is that we will need to generate and transmit a great deal more electricity than we do now.
I'm not going to play "Whos is bigger" with you. I will say that I made the transition to electric vehicles a long time ago and I'm currently on my fourth all electric car. So the transition you are talking about has already taken place in my life and, guess what, the electric grid didn't even notice it, not to mention that my electric bills are lower now than they have ever been even though I buy only renewable energy electricity.
Yes the grid can handle one or two electric vehicles per street, but that is a far cry from an electric vehicle in every household, let alone replacing all vehicles with electric vehicles. Several cities in the USA are already suffering from brown outs, and this will only get worse as more people switch to electric vehicles. And then there were the massive power outages in Texas last winter, if everyone had only electric vehicles, the situation would have far worse, as traffic would have virtually stopped in a day or two.
Another way to look at this is, as more people switch to electric vehicles, the electric utilities will see better utilization of infrastructure and have more funding to make it better (dollars that previously went to gas and diesel capture, processing, transport, and dispensing).
After buying Evs owners are much more likely to look at solar, geothermal and other technologies that reduce our reliance on the grid. Solar did not make sense for me personally because of my property but I now buy my energy from a solar energy farm. Electric vehicles will be the first step for many consumers to reevaluate how they utilize and receive power.
