If I had to guess, they have thought of this beforehand.The charge ports on our Tesla Model S is in the side of the rear taillight about as near to the end of the car as you can get. Even so, we often have to back right up to the concrete parking chocks for a Supercharger cable to reach.
The NACS port location shown on the rear of the Gravity would not be within reach of those cables. Even assuming Musk plays even-handedly with Lucid for software access, a Lucid would only be able to use a Supercharger equipped with one of the longer cables that Tesla is supposedly installing at some stations.
It's just one of the reasons I persist in a dim view of the real prospects of relying on Tesla for charging a Lucid.
The red circle is where the charge port is on a Tesla:

Another thing to note is the port is angled. This probably gives a better reach instead of straight side plugin.
