I apologize for not following this thread diligently, so I'm probably
missing a few things. Cor and Roger are doing a fine job, and I agree
with their responses. I do have a couple of (hair-splitting) comments to
add, though.

Roger, let me try to clarify my concern...I take the 20A coil [cord?] and plug
from
the charger in my converted car and plug into the adapter. However, it is an
unsafe
circuit. I have connected a 50A rated source to a 20A circuit with
no interconnecting protection device.
That's perfectly fine. People do it all the time. For example, there is
no reason you can't plug a string of Christmas tree lights that draw 0.1
amp into a 15 amp circuit.
If I have a large scale NEMA receptacle system, I cannot prevent people
from using "bad equipment" or "bad configurations of equipment".
Yes; and that is a potential problem. UL, NEC, and SAE requirements are
voluntary; they do not carry the force of law. People can (and do)
whatever they please, whether it's safe or not. Anyone can sell and use
anything in the USA, with or without UL/NEC/SAE compliance.
You can't stop a fool from plugging in a 1500w electric heater that
draws 12 amps through an extension cord only rated for 3 amps. The
extension cord burns up! The 15 amp breaker on that circuit won't trip
unless the melted cord SHORTS. Hopefully, people learn from their
mistake, and won't do that again!
Likewise, people routinely plug (say) a coffee pot and a toaster into
one kitchen outlet. They discover that if they use both of them at once,
the breaker trips. Not unsafe; but inconvenient. They learn not to do
that, too!
Plugging in an EV is no different than any other AC appliance. I have
confidence that the electricians who would wire a parking lot with AC
receptacles for charging EVs will know what they're doing. After all,
it's already been done for decades to power block heaters, street
lights, etc. (If they don't know what they're doing, they'll soon learn!)
And, I am confident that people will figure out that there are good
ways, and bad ways to plug in their EVs... just as they have for all
their heaters, toasters, and other gadgets.
Some think we need "safety police" to enforce strict new standards for
EVs that don't apply to anything else. The trouble is that most of this
has nothing to do with safety (or they would apply it to *all*
appliances). It is instead driven by greed (how can I make money off
this), or protectionism (how can I stop EVs from threatening my ICE market).
