Given the software bugs they're currently fixing I would expect it later rather than sooner. Unless people are signing something at delivery, Lucid could have a problem with what they're advertising on their website vs. what they're actively delivering. I saw this -
"Throughout your trip, you can interact with Lucid Air in a variety of ways. With Alexa Built-in, you get deep integration of in-car controls just by talking. Alexa can help you adjust your seat heaters, lighting, sunshades, navigation, and more. DreamDrive driver assistance offers peace of mind. And Surreal Sound™, Lucid’s available 21-speaker immersive audio system, elevates the entertainment experience. Air is even compatible with Apple CarPlay, Android Auto, and countless other apps."
maybe they get away with using the word "compatible" but when you see no * anywhere on that statement it's kind on insinuating that the car is equipped already. All it will take is one frustrated customer to potentially look into legal action.
