I looked at the current Lucid website, and I'm no longer seeing free charging. If I go to "Design your Lucid" my recollection is that it showed up underneath where User Experience is listed. If I look at new inventory, I'm not seeing it either.
Since it's not a listed feature, I wouldn't expect it to show up on the order agreement, and if it's included I can't see why they wouldn't list it.
There are a few complications with offering free EA charging when EA doesn't have the best reputation, and telling prospective buyers that they will be getting an adapter for NACS, implying that they will have choices. I don't know what Lucid has in mind, or how many people would have decided not to buy the car had it not come with free charging. There might be some, but if you look at the total cost to Lucid for supplying charging, and divide it by the margin from selling a car, you'd be able to figure out how many sales they could afford to lose. At this point, I have no idea whether offering free charging benefits Lucid, but they never made it front and center with respect to marketing.
