Can i install a 14-50 with no neutral?

Merry Christmas
Older oven/cooktops do, they regulate the burner heat by combinations of 120/240 to the eyes. 120 for low heat, 240 for high, some have multiple elements (four wire burners) to accomplish temperature control. Most modern appliances no longer use that, but we are assuming residential loads.
With designs in the global market, every single vendor of new equipment could adopt their international --- no neutral design --
to the US market. And we could be done with neutral for 240V loads.
 
A less quick search would show fake UL and CSA certification on most -- if not all -- of those adpators. Bad idea.
CARB screwed up - the automakers screwed up.
I can't control what people plug in, the HOA did state the load is 240V for a EVSE, and thats what they asked for (but with a 14-50). My boss was very clear on load, that the 50A receptacle will supply only 40A continuously, in emails, proposals etc. Who knows what will get plugged in in reality, some of these may get used for welders or pottery kilns a home machinist or wood worker with a lathe or whatever else people put in their garages. They are only willing to pay for two hots and a ground so a 6-50 is what they get.
These are the receptacles we are using they seem well made I'd recommend any professional EC use these and the EV people can 'fix' their products to ship with the correct North Amercian cords. :

Any properly *listed* apparatus with a 60-50 plug will either only draw max 40A if it's continuous (EV charger, kiln) or will only draw between 40-50A if it's *not* continuous (welder, saw). So you are just fine putting that receptacle on a 50A breaker.

It's already been said but it really is stupid that EVSE are shipping with 14-50 plugs, since an adapter for a 6-50 plug to a 14-50 receptacle could be a fully legit thing, but vice versa never can be.
 
A while back I saw a video of an EV that had the charging plug and connector literally explode off the side of the car because it was said the owner used an adapter. Luckly the owner was walking away far enough from the car when it happened.

Well if it was off the side of the car then that's a totally different type of adapter. And frankly, who knows what happened there, I'm skeptical we can blame adapters in general for whatever caused that.

Looked like a public charging facility. I don't know, but are all cars able to use the same connector that they provide? I kind of remember Tesla has their own design.

In this country there is basically J1772 and Tesla, now also known as NACS.

A public charging facility would likely support high voltage DC, but I'm not seeing how an adapter would defeat the inherent protections that prevent supplying voltage to the EV until the EVSE tells the EV what is available. Maybe there's something I don't know, or maybe the adapter was being used for a purpose it wasn't intended for.

There is an adapter that allows a non Tesla connector to fit the standard Tesla plug, but I don’t know if there is one for the other way around. I would think so.

It could easily be done now, as a lot of appliances have inverter controlled motors now. Dryers only require a neutral because manufacturers don’t use a dual rated drum motor for 208/240.

That was a Freewire unit, and the fault originated in a battery cable inside the charger (it was a battery buffered DC fast charger).
The adapter was not the problem, it's just the first thing that the "AFC" like DC surge happened to hit. The company, Freewire went bankrupt, though there's a new owner trying to bring the product back.
