feeder taps exploit for ev charging?

goal is to have this in all meter bases in usa ready to plug in an evse. some people hate the look of utilty boxes, Also cost per address. also we need the evse to set the breaker size so a cheap small or large can be plugged in. goal is no electricains needed for evse swapping. Nema 14-50 has failed us for ev use.
Might not be the best place, an electrician forum, for the "no electricians needed" pitch.

But that said, to the OP, is this what you had in mind:

Yeah there are contraptions like that that could certainly be slick and easy. I see two major problems though: grouping of service disconnects is going to be an issue, and also getting widespread acceptance by power companies.
Our utility will not permit any of the plug in meter adapters, such as transfer switches or solar connections. The blades of their meters have temperature sensor to warn of a connection problem, and the meter mounted device adds a blade/socket connection that is not monitored for temperature. If the temperature gets high enough, the internal disconnect in the smart meter will open.

In addition, meter mounted transfer switches and some other meter mounded devices require the connection of a neutral jumper to the meter socket. There is no available termination point for this neutral jumper in any of their approved meter sockets.
 
PG&E just changed the tap style MSA's from being one offs to being a tariff, so there is now just a standard price to install them.
Thats cool, and dont get me wrong, I think there should be laws standardizing utility rules and not allowing them to disallow things that should be allowed and make things cheaper and easier for everyone....but until that day, 90% of us are subject to them not allowing such things.

What happens if the meter is nowhere near where a car would be parked? What makes you think that everybody wants an EV? We can't even get the utilities to allow an emergency firefighter disconnect as part of their approved meter bases. That's a much more worthwhile cause than some silly EV charging plug that won't be used and will cost the utility money that gets passed along to us whether we use it or not.

I don't have a horse in this race, just an observer. Here's the list of the yes areas:
ConnectDER has three types:

Not every possible type of MSA is made, and not every utility takes every type. The fragmented nature of all this is indeed awkward.
And you can't stack a MSA on a MSA pretty sure anywhere.

What's the specific ask there?
Around here the firefighters just cut the tag and pull the meter. At least they used to,
as I've heard some areas don't out of a worry for a spark, others still do.
