So 110.3b is telling us to fallow the instructions from manufacture, tesla is telling clear do not use gfci, but the other 625.54 nec is asking for gfci, so on this case what you're doing? Is not a wall charger is a nema 14-50
 
Manufacturer’s instructions cannot override code requirements. If the receptacle is installed in a location that requires GFCI protection, you must provide it.
Tesla is saying (in a roundabout way) that the device cannot be used in a location where the receptacle requires GFCI protection.

Does Tesla say that about the basic charge cord included with the car or the wall charger? The cords frequently get connected to 15 amp 120 volt receptacles that are GFCI protected with no issue. Not sure why using the 50 amp adapter would change that.
 
I think there is some confusion. The user manuals for Tesla Mobile connector do not say that it can't or shouldn't be plugged into a GFCI protected receptacle or circuit. And anyway, any kind of cord that plugs into a receptacle is not installed equipment and really not under the scope of the NEC; anybody can plug it in and it either works or it doesn't, but the product standard for the cord and plug is what's supposed to keep things safe. So there is no conflict.
