In the teaser clip for tomorrow's installment in the "Road to Gravity" series, three of the Gravity shells going through the paint shop have a charging port at the front of the car, two have charging ports at both the front and the back, and none has one only at the back.
I wonder how late in the game they made the decision to go with a NACS charging port at the back. I listened to an episode of the "Batteries Included" podcast where the hosts all said that last week's NACS announcement was a given, old news. But the pre-production release candidates make it seem like that was not the case.
