My issue is communication, not whether CarPlay is coming this Friday. It is a sad state where we have to make jokes like this due to no communication. They stated dates in the public, did not make those dates and are now silent. It isn't too dissimilar to what they did with the Grey color, offered it on their website as an option, then had issues delivering, communicated various things to us along the way and then went silent for stretches. The "why" isn't as important to me. Just acknowledge the delay and what your new timeline is that you are hoping to make.
I also think they need to be more forthright on the website, get rid of the vagueness of "compatible" and just say that they hope to have CarPlay and Android Auto (or whatever it is) soon. Even reading "compatible" entirely in Lucid's favor, at some point "compatible" times out.
I know how customers react to a delayed flight. Agents just post that your flight was delayed one hour and are silent as to the reason. Three hours later, they have not updated the estimate or told you why you have the delay. Lots of pissed of customers at this point. You finally board the flight and the pilot comes on and tells you "sorry, there was a series of thunderstorms and pop-up thunderstorms that resulted in ground delays, etc.". You then turn to your spouse and ask "why didn't the gate agents just say there was weather in the area and we will give you an update when we get an update, but based on the current weather, we are hoping for two hours".
