Truthfully I don't think that's in the works. It would be some strategic sense as the two brands do compliment each other in some ways, but I would expect that Apple would already be involved with whoever they're planning to come to market with. In any case, I don't think it's important to Lucid being successful, they have an amazing product, a ton of money, a great looking pipeline and the land to build on to grow with them as they continue to grow.
As with anything, things take time, so this will take a little while (18 months?) to really get rolling, but then it will just grow and grow. I mean just look at Tesla - can you believe the Model S came out in 2012? It's already close to a decade old!
