Yeah at some point they would combine at least, I think. I’m not certain about US American standards.
Here in Switzerland, and in Germany too, we use the TN-C-S system (terre neutre combiné séparé) at least for any recent buildings.
That would usually mean that you mustn’t combine ground and neutral within your house (behind your breaker box). Otherwise RCCB / GFCI breakers can’t work either obviously.
I could see car chargers being wired up a bit specially, I have no idea about them to be honest, but surely they want to be able to check for ground faults as well.
