It is a matter of whether the media/navigation experience is something Lucid considers their differentiator. If they do, then it makes sense for them to invest and develop on their own. But if so, they can't leave it half-baked (well, they can, but then the differentiation would be "we suck and the others don't")
Also, when you are a startup with limited resources and too many areas where you want to differentiate, you have to know you can't focus everywhere all at once. So you start with something good enough (like Android Auto) until you can create something that is a true differentiator for you. Creating an entertainment system that does basic andoid auto and apple car play is as commoditized as it gets these days. With the computing hardware Lucid has, it should be a walk in the park doing this. I can see why it takes a few months, but then Lucid has been trying to do this for years now.
I have only had this car for a month now, so I am not as miffed as some of the others are about this. But even running v2.6.0 on my 2025 Air, I usually like using google maps on my phone. Lucid has ways to go before their media/nav is a differentiator.
