In the US it is not common. In EU the majority of EVs carry a cable in the vehicle for level 2 charging. At first I found it strange, but if you provide the cable instead having it built into level 2 EVSE (charger) its one less thing that can be broken or vandalized.

This is about parked cars. If you park you car and leave leave it with a removable charging cable connected to a socket in the curb, someone will just unplug it and walk away with it.

If I have to bring my own, it's one more thing of mine that can be broken or vandalized.
